  1. WHAT IS THE TRUE EXPERIMENTAL TWEAK THREAD ALL ABOUT? I have always wanted a thread where any subject is possible. No experiment is too crazy to add here. No idea is too bold to reveal. Take it away! Enlight your thoughts and share your ideas how to improve SQ and how not to. Anyone can encurage and educate you but no one should let you down, deminage you or simply move you to another thread. Everyone is welcome as long as they accepts a different way of thinking! TOPIC DIGEST With a little help of @austinpop I have realised that this thread is all over the place. Even if this is one of the fundamental ideas behind this thread, it could be a good idea to sum-up the things that have proven to be beneficial to SQ in this thread. I will keep it plain & simple. Remember that these are essentially my own findings in my own setup with Tidal FLAC and Tidal MQA as source. As always YMMV! LAN 1. Cat 6a U/UTP 500Mhz ethernet cables sounds better than Cat5, Cat5E, Cat6 & Cat7+ in my setup. Ghent Audio Cat 6a ET02 with JSSG shielding and Metz plugs rules them all. 2. Network switch improve SQ with input on port 1 and output on the last port. Possible explanation is QoS and also that the ports are in different magnetic boxes inside the switch. 3. Using a AQVOX switch with better clock improves SQ compared to a D-Link DSG-105 network switch. 4. A wireless adapter/wireless bridge/router in client mode into a network switch sounds better than battery powered FMCs and hardwired LAN. 5. Router vastly improves SQ with a floating LPS and even more if the floating PSU is connected to a DC blocker trap filter. IME a router upgrade could be beneficial to SQ. 6. Galvanic isolation/DC blocker in the signal path pre the router improves SQ. 7. Wireless adapter vastly improves connected to a floating IT. 8. RJ45 socket enhancers seems to be more efficient on port 4 & 5. Don't ask me why! GND 1. Grounding a metal chassi network switch to a tourmaline grounding box greatly improves SQ. 2. Different tourmaline grounding boxes improves the sound signature in different ways. 3. Grounding the DC negative terminal of the floating SMPS works great. In my setup it sounds best connected to a grounding box instead of to the power strip safety ground receptacle. Just be aware of possible leakage loops between various network devices. A big thanks @JohnSwenson for this tip. USB 1. Covering the outer USB barrels with electrical tape improves SQ slightly with unshielded USB cables. Capasitive coupling between metal barrel and pins? 2. Uptone Audio´s USPCB improves SQ. 3. ATL Hi-Fi´s 8 conductor USB cable with dual unconnected shields (5v+GND & Data- & Data+) with JSSG loop improved SQ compared to other longer (<50cm) USB cables that I´ve tried. DC 1. Network switch sounds best with dual floating PSUs or battery power (but very important to disconnect the battery charger while listening to music). Dual floating PSU is slightly better than battery power, but battery power is slightly better than single floating PSU. 2. Powering several devices with a single floating SMPS sounds better than powering the very same devices with several battery supplies. Also, powering several devices with a single battery supply sounds better than using multiple identical battery supplies. Self-inflicted noise? 3. Canare 4S6 starquad does improve SQ where ever applied. Canare 4S6 with JSSG seems to be even more effective. Thanks to@JohnSwenson! 4. Grounding the DC negative output of a floating SMPS improves SQ. Grounding the chassi/case decrease SQ. Be aware of shared ground paths since this could potensially decrease SQ. 5. Dual LT3045 ultra-low noise voltage regulators in series with 1v drop-down close to the powered device improves SQ quite dramaticly. 6. Kemet aluminium Polymer caps A750 series (25v 560uF) vastly improves LT3045 when added at the DC output. On single LT3045 the Kemet improves on both in- and output. 7. Panasonic FC series type A aluminium electrolytic caps improves on the PSU output terminals. AC 1. A DC blocker trap filter pre a safety isolation transformer improves SQ even though it is dead silent (no hum). DC blockers trap filter pre a floating PSU into a router vastly improves SQ. DC stress reliever? 2. SQ improves when battery chargers is connected to a separate powerstrip connected directly to the AC wall outlet, bypassing the isolation transformer completely. 3. A safety isolation transformer with floating secondary improves SQ more than a Ultra Isolation transformer. A balanced isolation transformer with floating center-tap rules them all! 4. Daisy chained floating grounds (dual floating grounds) sounds better than a single floating ground. In my setup floating SMPS's improve SQ connected to a floating IT, even surpassing battery supplies. Thanks for the suggestion @lmitche! 5. AC mains starquad power cables greatly improves SQ. 6. AC mains voltage regulators improves SQ on the signal chain. Even cheaper versions are effective. Not as effective on high power devices such as active speakers and amp due to a still unknown reason.
  2. Hello, I have been using usbridge for almost a year with my Auralic Polaris (usb-dac) and Squeezelite. I control my system with iPeng. Dietpi v6.6 was installed in the headless version. After the update to 6.8, there was an issue. Usbridge has no sound output. I reinstalled Dietpi with allo gui (version 6.6). Sound was back. After an update to 6.8 again no sound output. Does anyone know this behavior? What could be the reason? Thank you
  3. Bricasti M1 > M5 > M12: Network Player - Member REVIEW w/OEM Response from Brian Zolner President/Owner Bricasti below s Hey Guys - I have been going back and forth between what to go with for a Ethernet Network Media Player - either Innuos, SOtM, Sonore, Uptone, Bricasti M1 Network Player or M5, etc. I have a thread dedicated to working toward this decision and got some fantastic help from many CA members. I learned so much and in such a short time. This forum is Fantastic - so many people are so helpful and I appreciate it very much. I am including the link below to anyone interested in that very educational journey. Great stuff if you are interested in Innuos, SOtM, Sonore, Uptone, Bricasti Network Player or M5 I purchased a bunch of these product to try and learn for myself to be sure. I did not want to question my decision with any what if's and wanted the best sounding option for me and my system. I ended up going with the Network Player Option installed in my Bricasti M1SE DAC and I wrote this feedback to one of the best people in all of Hi-End Audio, Brian Zolner President/Owner/Designer Bricasti Design. His digital and analogue products sound absolutely fantastic and the build quality is second to none and the support is as good as it is anywhere. All made by hand right here in good old Massachusetts, USA. I asked Brian if it would be OK if I share my thoughts with the super helpful crew - the CA members that were so important in helping me get to this decision. He said no problem I also asked if he wanted to respond and comment and he provided some great insight below my feedback on his thoughts on the M1, M12, M5 network players and USB audio. I am glad to be able to share this with you guys. I will send Brian this link and I am sure if any of you have any questions or feedback or thought that would be fantastic. We will get you all the info you need. This is some seriously good sounding gear and its a lot less money than the Aurender and Lumin and it blows their doors off! Also, I would love some idea's and feedback and any idea's really now that I am all in with Ethernet audio what is my next step? One member told me to buy The Linear Solution OCXO Audiophile Switch. (link at bottom of the page). This is supposed to provide a great bump in SQ and it is $679 and comes with a dedicated purpose built Linear Power Supply. Please share you thoughts on this or any other upgrade that can help me get the most out of my Bricasti M1SE Ethernet Network Media Player. Subject: Re: Feedback Send to Brian Zolner and Joe at Bricasti Hey Brian and Joe, I wanted to reach out and thank you both for the very kind and outstanding service installing the Bricasti M1SE Ethernet Network Player option in my M1SE DAC. Guys, it is absolutely fantastic! It needed about 40 to 60 hours of burn-in to get to where it was going and honestly the upgrade over that time was substantial. I get that some people don't believe in burn-in and others like me clearly hear it but I am just telling you guys this Bricasti M1SE Ethernet Network Player option is absolutely fantastic. At first I was strongly considering the M5 just because I already own all of the premium - supporting USB Gear and thought it might be great and I am sure it is but honestly guys in all fairness I didn't think the Bricasti M1SE Ethernet Network Player option would end up being this good? Man is it good! I thought it would be good and/or even great but it surpassed even those expectations and that's not an easy thing to do. I am looking for an awful lot out of my gar and I had some premium gear it needed to stand up against. I can speak from first hand experience about this Network Player option and how it compared to all the similar other gear listed below. All my thoughts are in comparison to the gear listed below. I was able to do a/b verse some really good Ethernet / USB options that are some of the hottest, best selling products going and I assumed from an a/b it would be close and/or maybe I couldn't even tell the difference but this is where my non-audiophile wifey serves as a sort of blind test. Yes her ear has evolved but she is not an audiophile. What the Bricasti Network Player option does that is so much better than everything else is actually something you never even knew was missing until you hear it and then remove it. It jumps off the page during A/B's. Sometimes A/B's can be tough but here it stands out as clear as day it was simple. To test myself I asked my wifey for her help and what she thinks. I set up the Sonore/Uptone Combo and then the SOtM/Uptone power supply combo and the Bricasti Network Player and mixed them up and she picked it out each time. She actually picked out the SOtM over Sonore also so maybe her ear is getting better than I think but she heard it and picked it out clearly and simply so that reinforced what I already knew but wanted to check it. Bricasti Network Player is so much more direct and decisive. It's immediacy and directness just can't be missed. I was like "yes, yes, oh man yes"! "Thats what I am talking about" and you know what - those are far and few between these days so when it happens you REALLY appreciate it. Thank you It not like it is a little warmer and a little clearer or it widens or deepens the stage or something like that which by the way it does all these things but that's not my point. It is immediate, decisive and startlingly quick. Its got jump and you are just much closer to the event. It was a combo of heightened transparency with just layers removed and more information magnified and exposed in all its greatness. Also, I want to make sure to note that I am not talking about being more upfront either because it offered a deeper stage and the voices are actually pushed further back which normally I don't prefer. I actually like that dynamic and sort of upfront sound as a rule but that is not what this is. This does it totally different! It does it the only fashioned way. It earns it. This is no designers voicing choice, this is simply a much more robust and substantial component. It performs at a much higher level and it is shows on so many levels. Vastly better separation and delineation in that more direct package. The stage opens and the walls expand and out comes a richer and more layered and more natural presentation. Man that separation is just fantastic! I just can't get over that open space it puts around everything and the air and the extension go on and on. It's just that every item is so sharp and precise and magnified in 3D space. Everything is tighter and wider and deeper and it all just holds together so well and is so confident and that heightened image precision is such an enjoyable effect. I don't want to touch anything - this the best sound I've ever had and I'm ecstatic! Better than analogue IMO. I am sure there are some uber turntables that will out do it but pound for pound I doubt it IMO. I was impressed at this much closer to the event effect. It's kind of hard to articulate but I think this might shed a little more light. Sort of that same effect you get when you have a great DAC or CD player and then you remove the preamp. The only thing with removing a great preamp is you gain that great immediate directness but then lose all that greatness that a great preamps provides but that increased directness is such a desirable effect so many people do it. I did it but then you get a great preamp and you say man I love the directness but I am giving up so much to get it. Some big time trade off's and many go back and forth. I know I did for a while. So this new Network Player upgrade was like keeping your amazing preamp and all the great benefits the pre provides while still getting that great directness a preless set up gives you. Best of both worlds! How often do you get to have your cake and eat it too? Well that is what happened here IMO with this so I think you can see why I am so happy about it and hope this does a little better job of explaining the main effect of this Ethernet Network Player option I added to my system. This preless type directness while keeping all the greatness of a preamp is worth the price of admission all by itself but there is more. All that directness has a great effect on the bass which is tighter, cleaner and more nuanced with much better separation. There isn't any more slam or power. It is not rounder or warmer which some may prefer but it is different. It is more nimble and lighter on its toes with more precision and definition. I don't think its any less powerful but it's different sort of like my Magico speakers are. People think or feel with Magico's sealed Aluminum cabinets there is less bass when in actuality there isn't any less but it is faster and more defined but some interrupt this as less bass but I don't agree but also each to their own. I find it to be a nice improvement and upgrade but I can see someone that likes to listen to a lot pop or rap music they may refer a thicker or rounder sound but everyone else will love this IMO. I will take quality and precision over quantity every time but that's just me and everyone is different. I want take a moment to thank you and your company again for your approach to supporting the folks that purchase your gear. Premium Hi-End Audiophile gear is quite expensive and so many of the top Hi-Fi companies come out with a new model every few years and that kills us. We need to sell our old one to get the new one and that makes expensive gear insanely expensive to own. Many people like me want the most recent and best gear they can afford. You guys make this possible and care more about your customers than any of the other OEM's and we appreciate it very much! You guys are totally different from the Vast Majority of high ends OEM's. Also, this feedback was not made in a vacuum. Here are the items I had in my system that I did an A/B with that allowed me great insight into how your Ethernet Network Player option worked verse the others. Some of these I only owned a for a short while because I knew there was no contest. Most have either been sold or are in process of being sold on Audiogon because your Network Player made them obsolete. I am keeping the JS-2 and P10 for my new system set up.

Sonore, SOtM and Uptone Audio in my opinion changed the world in regards to the USB landscape and in a huge way. There are a few others as well. They brought, real world price upgrades to USB that made semi-inexpensive gear better than super expensive legacy products from just a few years back (CD and SACD Players) and this changed the game. Now it appears you have changed the game on the Ethernet side. I call tell anyone out there that doesn't own a Bricasti M1 is to buy the M5. I am not sure how the M5 sounds because I have not heard it but if it sounds anything like the M1 Ethernet Network Player then there is nothing that can touch it. Great job and thank you guys. With your permission I would like to share this personal email on my forum post and if you are ok with it any of your responses as well. People are waiting to hear my thoughts so I thought I could email you and inform them at the same time. Thanks Frank Fsmithjack Subject: Re: Response / Feedback from Brian Zolner Bricasti President/Owner/Designer to Frank Smith / Fsmithjack Frank, Thanks for all that commentary, and well guess only thing I can say or add is once we got the LAN working in the M12, and then the M1 ( it’s the same streamer used in all products) I never went back to USB, clearly better even just connecting with 50’ cat5 from my server to the M1. We do all shows with the LAN and try to convince users this is the way. I feel that regardless of the cables and power supplies and clockers etc for USB that seem to make some differences, one might say they create differences and subjective to if its better or not, but I feel USB is fundamentally flawed and when the player or renderer is installed directly in the M1 it eliminates all the issues of USB, it removes it from the computer, and places it in the M1. We made our own player, running on a linux core on an ARM processor, runs off the linear supply in the M1 too. so no extra processors running as with a PC where the computer is doing all kinds of other co processing, switch mode power regulation on the PC mother board etc. But in the end of all that stuff, this approach eliminates it. For the sound of USB, People are fooled by things and as you point out someone might like the effect of the USB, but I think what we get with the streamer is true sound reproduction with no jitter and noise added to make the sound dance a bit, I hear it clearly on my Tidals, and our M28s, no loss of bass at all for me, but tight clear and excellent extension, no bloating. The M5 was made so that a user could run off the network or PC without using USB, I feel the AES is the best as removes these issues. But installed in the M1 or M12 is the best, direct I2S to the DSP and then to the DAC. The M5 with AES is darn close to what you have, I have done a lot of listening and that was the idea of that product to offer great playback and no USB for anyone and any DAC. Enjoy it, I know it changed my life, my server PC is in another part of the house and I run it all from Jremote, there is just no other way to play, besides the sound there is the convenience factor and I play tracks from my phone or stream from it to the M1, or the server, or the NAS or any PC in my home, all the computer stuff goes in another room away from the listening room. It’s a network and that is what starts becoming interesting and you don’t get that with USB or any other point to point interface. Go ahead and share the story, its what we hope others will find out too. Brian Subject: Re: Response / Feedback from Joe at Bricasti to Frank Smith / Fsmithjack Hi Frank, thank you for great write-up! Enjoy your M1, if you ever need anything just let me know. Thank you again, joe http://www.bricasti.com/en/consumer/m1se.php http://thelinearsolution.com/ocxo_switch.html
  4. Observations In his article “Computer Audiophile Turns 10 Today” Chris Connaker, the founder of Computer Audiophile, noted of Apple USB ports: "April 11, 2008 - A USB Port is Not a USB Port - So, what is the deal? Apple's design of the USB architecture in MacBook/Pro models is flawed in my opinion." We have recently witnessed the rise of an understanding of the need to clean up the signal when feeding DACs via USB from computers: this forum is filled with solutions. From my experience, using an Audioquest Jitterbug into various DACS (when fed from my MacBookPro via USB) has, on all occasions, noticeably improved the sound. Questions So I am wondering: - In relation to USB output, are some Apple machines “cleaner” than other Apple Machines? (So, for example, does a MacMini provide a cleaner USB output than a MacBook Pro?) - For machines that have more than one USB output: I know I am able to access information on the USB ports from About This Mac/ System Report. But once accessed how would I determine which port is "cleaner"? - Have any of you hardcore Mac Heads done any comparisons on the USB outputs of your Macs? Or compared Macs?
  5. As USB flash drives with capacities of up to 1TB start to become available, I would like to know if there are any advantages (or disadvantages) in using flash drives instead of solid state and hard disk drives for music replay from locally attached USB storage.
  6. Hi Everyone, I recently delivery of the SOTM tX-USBultra and posted my impressions on another thread, but here it is again for those interested in this device. Initial impressions of SOTM tX-USBultra: I got delivery of my unit yesterday, then I plugged it in my system in the evening. What I did is to critically listen to 3 or tracks on my system with configuration (1): (1) Nimitra (JS-2)>>Curious 20cm link>>Intona>>Curious 20cm link>>RUR (LPS-1)>>Curious 20cm link>>Brooklyn DAC. The system simply sounded fabulous, music just flows with a sense of realism and 3D especially after installing my two dedicated circuits (one for digital and another for analogue) Here I would like to mention that I upgraded my AO from version 2.0 to 2.10 and it made a significant improvement, then I upgraded to the beta AO 2.20 and the sound went to another level (more transparent, wide soundstage and better separation). Then I removed the RUR+LPS-1 and replaced them with the SOTM tX-USBultra powered by the second rail of the JS-2 at 12V (my unit has the 12v option) so configuration (2) is as follows: (2) Nimitra (JS-2)>>Curious 20cm link>>Intona>>Curious 20cm link>>SOTM tX-USBultra(JS-2)>>Curious 20cm link>>Brooklyn DAC. just out of the box without any burn-in, configuration 2 clearly elevated the sound of my system in all directions, most importantly to me, a sense of feeling that the music is so real and so clear you feel that the notes are sharper and more defined in the soundstage, a veil taken off the music! (a cliche but it accurately describes my experience) I didn't try to power it with the VR MINI because I use it on the Brooklyn and if I change this configuration, then it won't be A/B comparison anymore. My logic now is that I can improve it by freeing the JS-2 from feeding two units and keep it only to Nimitra and get a dedicated PSU to power the SOTM tX-USBultra, but too early now to make any decisions before I get my DC ammeter working. So (RUR+LPS-1) will be staying with me for a short time to do some A/B comparisons after 1 or 2 weeks when the SOTM tX-USBultra has settled in my system and most probably will be listed for sale. My learning is that isolation by ultra-capacitors is important but super clock with a good LPS can be more important. I hope this helps others on a similar path

  8. The iDAC2 – spilling the secret sauce (part 1) The iDAC2’s musicality has wooed – most recently the iDAC2 + iPurifier2 + Pro iCAN at the Fujiya AVIC Headphone Festival in Tokyo where the market is probably the most demanding on the planet. Source: iFi Retro Stereo 50 + iPurifier2 at Fujiya Avic 2015 | DAR__KO The Pro iCAN was one of the show ‘best sound winners’ so the small but mighty iDAC2 + iPurifier 2 combo deserve some credit for producing the digital-to-analogue conversion to feed the Pro iCAN. At the show, the quite technically proficient Japanese press asked us on more than one occasion why the recently-launched iDAC2 sounded so nice. And this is a press pack that has turntables in heavy rotation so they know their onions. This gave us the idea to put finger to keyboard. Source: 【候補多すぎ】ヘッドフォンç¥*アワード2015秋は週末までに公開致します! | 目福耳福 Fujiya Avic BLOG Bake-Off: the iFi recipe behind a really good DAC The following are our thoughts only. The application of the parts budget as common industry practice is similar to what we did in the iFi iDSD nano which is more indicative of <US$1,000 DACs. Often a very large part of the budget is needed for the digital platform (after all, we need a DAC Chip that headlines and a good USB processor). Power supplies and analogue stages receive the remaining budget. Hence, the three key cost areas in the electronics of a digital-to-analogue converter: Digital section cost - is much the same across the board, chipsets/clocks vary but slightly and software is usually ‘off the shelf’ like the XMOS firmware and off the shelf DAC Chips of usually comparable cost. In a USB DAC the USB Processor is usually the biggest ticket item before the DAC. Clocks and their power supplies often cost as much as a DAC Chip. Analogue section cost – from a simple double Op-Amp for 20 cent to things done much more extensively cost varies. The iDAC2 has BB Soundplus integrated amplifier and a discrete JFet and BJT Class A output stage. Further it employs C0G Capacitors and MELF Resistors for all signal positions, all this adds cost. Power supply section cost – Often USB DACs have minimal power supply arrangements with generic 3-pin regulators. If done more extensively, then the cost is higher eg iDAC2 uses ELNA Silmic Capacitors and Active Noise Cancellation® to eliminate the USB power noise. iDAC2 is no piece of cake Things are different in the iDAC 2: we started with a larger budget, we could have spent it in a number of ways, like more DAC Chips or different ‘fashionable’ DAC Chips or fancy clocks. Instead we chose to put the extra budget where it impacts most, namely analogue stages and power supplies. The iDAC2 has a similar cost digital section as with other DACs out there (and to our iDSD nano) but its analogue and power sections are more extensive hence its overall cost is greater so its pie chart area is larger. The proof is in the listening. Next time: Part 2. The Digital section
  9. I have a couple of USB problems: 1. When I connect my laptop via USB to my Korg DAC, it is downconverting hi-rez to 44kHz. This happens remotely from my server and locally, using QMusic, or foobar2000. The laptop is a newish Dell Inspiron 7000. 2. My Hipstreet Windows 10 tablet will not stream via USB to my Audiolab 8200CD player, nor to the Korg DS-DAC-10R. It seems to connect, but no sound comes out. I would greatly appreciate your help with these USB issues.
  10. Hi guys. My question is quite straight forward. I am running either a 16' run of USB out of Thinkpad, followed by an W4S Recovery into the DAC vs 3' USB into an Bryston DDC following a 20' AES/EBU cable into the DAC. I've had it set up both ways. Should either one be superior to the other? I have an idea, but looking for confirmation......
  11. I have some questions about digital interface limitations and am hoping that the more knowlegeable among you might correct any misunderstanding I have. I just upgraded my DAC, making the connection from my computer the weakest link in my digital audio chain. I am looking for the best solution that maximizes the capability of the new DAC while minimizing inherent down-sides of the different interfaces. My currect set up is: iTunes library on an external USB 2.0 HD -> MacMini (early 2009, 10.11.6) -> TOSLINK output -> Gefen Digital Audio Extender sender -> Cat6 cable -> Gefen DAE receiver -> TOSLINK Cable -> Schiit Bifrost Multibit. The MacMini is limited to 24 bit/ 96 kHz over TOSLINK. The Gefen DAE has the same limitation. The goal is to restore 192 kHz sampling rate ability for the DAC. The distance between my computer and DAC is currently 6 meters, but I hope to move my computer farther away in the near future. Here are the solutions I am considering. I'm not set on the linked products; they are included just to give a better idea of the proposed solution. MacMini -> Active USB 2.0 extension -> USB cable -> DAC: lowest cost, 25 m limitation, higher jitter MacMini -> USB cable -> USB-over-Cat6 extender -> USB cable -> DAC: 50 m limitation, higher cost, higher jitter http://www.gefen.com/product/gefen-usb-20-sr-extender-over-one-cat-5-cable-EXT-USB2.0-SR MacMini -> USB cable -> USB-S/PDIF converter -> S/PDIF cable -> DAC: higher cost, more suceptable to interferance https://wyred4sound.com/products/dacs-converters/%C2%B5link MacMini -> USB cable -> USB reclocker -> USB cable -> DAC: 10 m limitation, higher cost https://wyred4sound.com/products/digital-converters/recovery Switch to Roon, ethernet -> Roon Endpoint -> S/PDIF Cable -> S/PDIF Reclocker -> DAC: lower jitter, highest cost, most effort https://www.hifiberry.com/shop/bundles/hifiberry-digi-bundle/ https://wyred4sound.com/products/digital-converters/remedy-reclocker Thank you for your help.

    I2S Computer Build

    I am doing preliminary planning for a dedicated audio computer to replace my modified laptop. My W4S DAC accepts I2S input. From postings here I2S sound quality is at least as good as USB and probably better. Pink Faun and maybe others make an I2S out board. So I am thinking of using I2S and maybe building in a good USB output to make direct comparisons. Anyone have experience using I2S out and into their DAC, comments on SQ, tech issues, etc. Thanks.
  13. Hi all and @Archimago Is the issue/s that's described here by Archimago, regarding 8kHz packet noise, still an issue with mobile USB sources running off battery, like an iPhone, Android phone or mobile DAPs? i.e. USB sources not connected to mains power at all? Or is it still an issue with mobile battery based USB sources too? Cheers
  14. I need a mic to talk to friends when I am playing games, but I hate using over the ear headsets; for me, they are uncomfortable, they give me a headache, and they hurt my ears after a while. My problem is that over the ear headsets are the only way I know of to have a sidetone, I cannot use a headset without a sidetone. I would much rather use my earbuds/in-ear headphones. My question is what do I need to be able to use in-ear headphones and still have a sidetone so I can hear myself? I tried to figure it out myself but I know absolutely nothing about this sort of thing. I don't really want to spend a lot on this, whatever is cheapest will be good enough for me.
  15. Hi, I am looking for any possible suggestions/ user reviews, etc for a Y Split USB Cable (one USB B going to two USB A). Anyone have any experience yet with the brand new IFI Gemni USB 3.0 Y split USB Cable? I am thinking about buying one to use with my IFI Micro iUSB 3.0, bit was hoping to see some reviews or opinions from CA Members first if possible? I have tried the Pangea Preimer Y Split USB cable, and for the price ($99-$150), it really wasn’t too bad, however I am looking for “more”. I also had Ghent (cable maker in Hong King) make me a custom Y split USB Cable, made from Silver plated copper, Teflon insulated, good copper braiding and a JSSG sheild (John Swenson technique attaching an external wire from one end of the copper braiding to the other, but not connected to the connectors). - The Custom Ghent cable had a bit of Harshness in my system and did not sound as good as the Pangea Y Split USB cable. Neither of these cables sounded as good as my Reference USB cables (to date), which are the Cardas Highspeed 2.0 USB Cables. (These are a split design (separated shielded cable for power and data), yet the USB A and USB B connectors both join at each end. Since I have the IFI Micro iUSB 3.0 reclocker, I want to use a Y split USB cable with separate USB A connectors (1 for power / 1 for data). Ifi has just released a brand new version of their Gemni cable (Gemni USB 3.0), so I am tempted to buy it. However, overall, I’ve notived not much mention of the original Gemni USB cable within Audiophile Reveiws, Blogs, Magazines, etc, so I’m a little unsure about how they “stack up” vs some more commonly praised USB Cables. The availability of USB Cables that come in a Y split design is pretty slim. Thanks for any thoughts or suggestions!!
  16. HI THERE IN AN ABSOLUTLY OPTIMIZED ENVIRONMENT AUDIO PC (AO,FIDELIZER PROCESS LASSO WINDOWS10 PRO AMARRA JRIVER) I CANNOT MAKE TO OUTPUT ANY SOUND FROM DE DAC CARY 200 TS THE DAC REGISTER THE SAMPLE FRECUENCY FROM THE PC BUT DONT OUTPUT ANY SOUND . I INSTALLED (CORRECTLY) THE WINDOWS DRIVER AND IS RECOGNIZED BY THE AUDIO SYSTEM OF THE PC. I ALSO TRIED WITH A MC COMPUTER WHO CLAIMS FOR NO NEED OF USB DRIVERS AND NO EXIT TOO. THE ONLY DIGITAL INPUT THAT SEEMS TO WORK TOTALLY IS THE OPTICAL THAT IS FEEDED BY A MCiNTOSH CD SACD PLAYER. VERY FRUSTRATING FOR ME BECAUSE THE DAC DOESNT HAVE ANY FACTORY OR MASTER RESET TO FACTORY DEFAULTS AND WE HAVR NO TECHNICAL SUPPORT HERE IN BUENOS AIRES. ANUY HELP WILL BE VERY APPRECIATED RECRDS WILLY

    SACD Ripping News

    Hi everybody, Maybe I am not posting this into the correct forum... but here it is : Anyone who knows how to do this can copy / paste this text where it belongs so that everyone hears about this news. I can rip any SACD stereo or multichannel on my recent Primare BD32 MKII, (with the latest firmware) so this one can be listed with the Oppo's and Pioneers among others. It makes ISO files (bit to bit copy of my SACD, as well as DSF files (as tracks) It works fine with the USB stick with the AutoScript folder (with 3 files in it) and together with ISO2DSD and it rips a 1 hour SACD in less then 15 minutes (over cabled IP network) I am a lucky guy ! Thx all of you. Koen.

  19. Hi guys, So, I have a little problem with my USB-Sound device. I've got a Soundcraft Notepad-5 connected via USB to my Windows 10 computer. Overall I am very happy with this device, except for one thing. If I play for example a short note in my DAW, the soundcard won't let me hear it. When I play the same note over and over again it will eventually pick up. To me it seems like it thinks that that one sound isn't worth playing through my speakers or something.. very weird indeed! Playing music etc. works perfectly fine.. Does anyone have a solution to this problem? It seems very odd to me, and I can't find anything on the internet about it since it is a fairly new device. I also have installed the latest drivers for it. Thanks in advance! Gerard de Graaf
  20. A Guide on how to get the most from your Schiit Eitr I recently began a quest to determine if it was possible to improve sound from the Schiit Eitr. There are three variables I knew to explore: USB Cable from source to the Eitr S/PDIF Cable from the Eitr to the DAC Power Supply (not necessary: LPS already used by Schiit) Where I am coming from: I listen using HD800S phones powered by a Kenzie tube amp and Brooklyn DAC+. I avoid powered USB hubs and connect the Eitr directly from a USB 2.0 port on my Win 7 Pro laptop. USB Cables Do Make A Difference My first experiment involved comparing the popular Blue Jeans USB 2 cable to the AudioQuest Diamond USB Cable, Type A to Type B, 0.75m. AudioQuest Diamond USB Cable Review Source was Tidal HiFi using non MQA tracks I was very familiar with. After listening using the Blue Jeans cable I swapped in the AudioQuest Diamond. The most immediate difference was in musicality: tracks were more enjoyable to listen to. Consider swapping a basic turntable for an LP-12 and the music becomes more "tuneful" as Linn used to say. To be more specific sound stage became wider, deeper and taller using the Diamond cable. There was more air around instruments and voices. Treble was silky smooth and I noticed more impact in bass. I heard more detail and it was easier to listen deep into the tracks. Advice: if you have a very revealing system and can get an AudioQuest Diamond on trial from a dealer try it for yourself. Bits are not always just bits and USB cables do make a difference. I have an interesting high-end S/PDIF cable on the way and will update once I have a listen.

  22. This is my first post so bear with me. I've used mp3 on cell phones etc for years but recently ripped all my CDs to both mp3 and FLAC using dB Power Amp. I am looking to setup a high quality 2 channel FLAC audio system using a NAS. I have an older high end Yamaha receiver which lacks HDMI. A Schiit Modi 2 is in my near future as is some 2 or 4 bay Synology NAS. Q1. Are those DAC and NAS a reasonably good choice? Will they just boot and play nicely together? Q2. In Synology Audio Station I would set the NAS to playback on "usb speaker" in order to get the FLAC out the usb port and into the DAC. When playing a NAS video presumably the audio portion of the video still goes over the eithernet [don't care if this also goes over USB port]. Q3. There seems to be so many Synology NAS models, including last years models still available from some on-line sellers. What do I need to look for in order for this setup to work? Is there a series that I should be looking at? [+, +II, j, se, play, etc] [I also have a 2016 55" 4K HDR TV but I don't think I will be trying to use the NAS to upscale to 4K, or even 1080p]. [on the TV side; the TV, Blu-ray, android box etc will play their audio via a HDMI switch with analog audio breakout connected to receiver input] Thanks John
  23. Wondering if anyone is connecting MacBook Air as a one computer config so one usb port is connecting to dac, and internal ssd as boot drive - whats the best sq solution in your experience: 1. Use another usb port for external hdd - ssd, or just a regular drive? I play mostly dsd; 2. Use the SD card slot and better sq or not? 3. Use thunderbolt external hdd, better sq? Audirvana manual recommends making sure the high speed usb port are dedicated to usb connection to dac, not sure if the 2 usb ports on macbook air is on same circuit thus shared, therefore am wondering if using the other connection options may imprive sq. Anyone can chime in on this? Thanks.

    ultraRendu & USB reclocker

    Hello all, I have a Wyred4Sound Recovery USB reclocker, which I used to place between my Auralic VEGA and Mac Mini (running Roon). Since I now have the ultraRendu, my VEGA is now fed directly from this device without direct connection from the Mac Mini. So the question is, would putting the USB reclockler between de Ultrarendu and the Auralic VEGA still make sense, as the ultraRendu already produces a low jitter signal? Anyone experience with this (or any other reclocker?)? How does this balance between putting another additional device (the reclocker) on the signal path? Thanks in advance! Rodrigo
  25. I am investigating how to improve the SQ from USB for my DAC8. Until now I have used a decent Chord USB cable, Jitterbug, ISO REGEN + USBPCB + TeraDak LPS, PUC2 lite + TeraDak LPS. So far my conclusion is that using a PUC2 lite with AES connection give the best sound. The only drawback is that it is limited to PCM 24/192. Sound quality is great, very clean, vert balanced with every instument in place. Using ISO REGEN or Jitterbug did not work for me. Jitterbug did not add or removed anything. ISO REGEN which is highly praised, sounds a bit better than USB only but it is not very significant as I expected. ISO REGEN + PUC2 lite is even more surprising. It is not as good as PUC2 alone. It emphasizes the lows but veils a bit the highs. It would nice to hear similar experiences and any recommendation for USB/DDC components that did significant improvement the T+A DAC SQ with USB. I am not looking for subtle improvements but ones that are significant, similar to what I get from PUC2 lite. Experience using Isolated/balanced power can be interesting as well.
