  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 reviel. Take it away! Enlight your thoughts and share your ideas how to improve SQ. 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 I, with a little help of @austinpop, 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 simple. Remember that these are essentially my own findings in my own setup with Tidal FLAC and Tidal MQA as source. As always YMMV! Ethernet # Cat 6a U/UTP 500Mhz ethernet cables sounds better than Cat5, Cat5E, Cat6 & Cat7+. # Network switch improve SQ with input on port 1 and output on the last port. QoS? # Using a AQVOX switch with better clock improves SQ compared to a D-Link DSG-105 network switch. # A wireless adapter/router in client mode into a network switch sounds better than battery powered FMCs and hardwired LAN. # Router vastly improves SQ with a floating LPS. # Galvanic isolation/DC blocker pre the router improves SQ. Grounding # Grounding a metal chassi network switch to a tourmaline grounding box greatly improves SQ. USB # Covering the outer USB barrels with electrical tape improves SQ slightly with unshielded USB cables. Capasitive coupling between metal barrel and pins? DC # Network switch sounds best with battery power. Very important to disconnect the charger while listening to music. # Powering several devices with a single floating SMPS sounds better than powering the very same devices with several battery supplies. Self-inflicted noise? # Canare 4S6 starquad does improve SQ where ever applied. Thanks to@JohnSwenson! AC # A DC blocker trap filter pre a safety isolation transformer improves SQ even though it is dead silent (no hum). DC stress reliever? # A safety isolation transformer improves SQ more than a Ultra Isolation transformer. # Daisy chained floating grounds sounds better than a single floating ground. In my setup floating SMPS's improve SQ connected to a floating IT. Thanks for the suggestion @lmitche!
  2. My current DAC only way of receiving power is over USB. I have the ability to power it over the USB and send it digital signal through S/PDIF, but I just ordered a SOtM sMS-200 and I would like to use it in my setup. I am wandering if the sMS-200 audio usb port sends digital audio signal as well as 5v power. I know some high end audio units strip the 5v power line out of a USB to remove a possible source of noise, so that is what made me curious as to whether the sMS-200 will power my DAC as well as send it digital signal. I have asked the question twice to SOtM, but there appears to be a translation issue and they think I am just confirming that I can send digital signal to my DAC via USB. I know that if it does not output power over USB then I will be forced to buy something like the UpTone Audio USB Regen to allow me to add power to the line cleanly from my linear supply. If anyone has insight on this issue please share your knowledge. If I need a device to add power to the USB line then I would like to order it now so I am not sitting staring at the sMS-200 waiting to hear it. Thanks guys. Mike
  3. Hi all Just wanted to ask if there are any PS Audio DirectStream DAC owners out there that have paired it directly with a Benchmark AHB2 power amp? I'm thinking of trying out this combination and I'm trying to arrange a demo for January but in the mean time I'm interested in hearing anyone else's thoughts, that's tried this combination specifically. Thanks in advance :-)
  4. I have 2 studio monitors and a streamer, all with smps, and very power consumption, like under 30 watt each. Smps devices pollute the power system so one needs power socket / Filter with individual filtering for each socket. I am interested in surge and spike protection to prevent the smps from running hot (we have a lot of Voltage variation here). The filtering / protection must be very sensible cause smps devices need instant current and usually sound less dynamic with filters. Any advice? Would like to stay below 700 stones... (European devices preferred, I have schuko plugs)
  5. Finally, about a month after receiving my JS-2 and MMK from Alex, I was able to be home, have the tools, and the time to do the installation. Here are some of my thoughts... THE GOOD 1. I've just turned on the Mac Mini (late 2014 PCIe Flash) plugged into the JS-2 and it does sound really good (I can't quantify the improvement, but it's definitely there)! 2. Fantastic service and support from Alex (Superdad). I had a few questions over the past few weeks, initially with the order, and then some clarification questions, all of which Alex responded very quickly to! 3. Really nice build quality on the JS-2 (see picture below). I personally would have preferred not to have any text on the front fascia, but no biggie. COULD BE IMPROVED 1. I consider myself reasonably "tech comfortable", but even so I have to admit that I put off the installation project more than a couple of times because of the rather scary-looking documentation - granted, probably every step needed is described nicely by Alex in the little booklet, but it's in very fine print (a tad challenging for my nascent presbyopia), and there are no pictures! Not one (well, except for the cover photo)! 2. Having said the above, Alex did very kindly send me emails with iFixit links, for the tear-down (first part) of the installation. However, one will still have to read the documentation very carefully to figure out the second part, as it (of course) isn't on iFixit... 3. What made it a tad more worrying was that the documentation was obviously prepared some years ago - the very first line says "Install this product only in a 2010, 2011, or 2012 Mac mini". Alex did clarify in an email that it would work fine on my 2014 Mac mini, and did also describe some of the differences between the documentation and what I would have to do for my newer unit, but it did add to my fears (and the complexity)! 4. Another problem was that the Torx 6 Security bit, which is required to open the late-2014 Mac mini, is not included in the toolkit that Alex sends out, so I had to purchase it from iFixit separately. 5. There is no documentation at all as to how to use the JS-2. At first I didn't worry because, after all, there aren't that many connections! However, for the first few minutes after turning it on my Mac Mini refused to start up, until I figured out that the "sense" cable was loose, and also that I had to have the little switch at the back set to "sense", and that the DC cable had to be connected to the DC-2 output (in hindsight it is obvious, since it is the output closest to the "sense" input)... SUMMARY In summary though, I have to say that the actual installation process is very, very easy to do - it just looks difficult to those of us accustomed to having pictures to follow-along to! The resulting sound quality improvement (at least to my "freshman" ears) also sounds pretty good! And again, Alex was fantastic in being very prompt and helpful with his email replies! I've provided some photographs of my installation below, as it may be helpful for others in the future (do note that in the second-last picture the switch/sense is set wrongly - I took that photo while trying to figure out what was wrong). Art p.s. As mentioned, for the first (teardown) phase, I used this guide from iFixit:
  6. Venom MPC-12A and MPC-12C Power Distributor Promotion MPC-12C & MPC-12A Promotional Packages (starting at $2139): Tax-Season Savings! The VENOM MPC-12 is similar in function to our traditional power distributors in that it is intended for normal audio and video systems that are not specifically computer based audio systems. VENOM MPC-12C The VENOM MPC-12 "C" is designed specifically for computer-audio, video and music-server based systems. Computer-media based music systems use several digital or processing components associated with computers (server). These devices are often made with commodity power supplies that put out significant amounts of power line noise. The MPC-12C was designed specifically to segregate or “firewall” the computer or video related components -- preventing them from polluting the performance of your high-end analog components. The MPC-12 "C" is Shunyata Research’s most finely tuned power distributor in terms of its system specific design and function. Essentially, the MPC-12 contains two separate power conditioners starting from the power inlet. In section one, The MPC-12 "C" uses Shunyata’s finest CCI™ (Component-to-Component Interference) filter arrays to reduce noise and enhance performance while still allowing for maximum current-delivery to even the most power hungry amplifiers. The other side of the MPC-12 "C", employs a custom-manufactured hand-wound air coil which literally fire-walls intense computer or video generated noise from affecting the components plugged into the second bank of six high-current/Analog outlets. VENOM MPC-12A The MPC-12 "A" has two independent zones of 6 outlets each, for a total of 12 outlets. This allows for the normal segregation of analog and digital components or between amplifiers and source components. The "A" designation stands for audio although it can also be used in all forms of audio/video systems. The two isolated zones will be labeled "A/V Zone 1" and "A/V Zone 2”. At the core of the MPC-12 "A"are Shunyata’s latest generation of CCI™ (Component-to-Component Interference) filters. These powerful multi-frequency noise-filters provide exceptional isolation for electronics without interfering with DTCD™ (Dynamic Transient Current Delivery) or electronics power supply function. The MPC-12 "A" has none of the drawbacks commonly associated with traditional forms “power conditioning” yet provides all of the protection and noise isolation that benefit electronics systems of all types. Complementing the superior noise isolation in the MPC-12 "A" are dual 12 gauge OFE 101 copper conductors. This massive 9 gauge aggregate conductor set insures optimum DTCD™ performance for any and all high-current draw systems. Surge and spike protection are included in the form of Shunyata Research'’s Surge module, which has had a virtually zero failure rate since its inception. Putting these elements together in a 12 outlet, form-follows-function package makes the MPC-12 "A" an incredible value. For those looking at the next big step-up from Shunyata Research’s critically heralded PS-8 power distributor, the MPC-12 "A" delivers on that promise. For those with the audio-systems that combine one or two digital components such as a CD player or Transport and DAC, the MPC-12 "A" model makes the most sense. For those with computer audio or video centric systems, the MPC-12 "C" is the best choice. The MPC-12 “A” and “C” models also feature on-board surge, spike and over-current protection with a built-in status L.E.D. indicator. For a limited time, we are offering complete high-performance power-distribution packages on the MPC-12 series of power conditioners. These are available on both the MPC-12A and MPC-12C. This all-in-one package includes the high-performance option of the High-Current VENOM-HC or ALPHA HC power cable and the new SSF-38 (stainless steel feet).

  8. I have Z77 chipset, 2600k, Win2012, Everything is tight and optimized, with a USB3 PCI-E card, and just one Intel SSD. Feeding my DAC over USB (DAC has it's own power). Been changing from a Corsair hx750 and an corsair vx450w and listening to the difference. Even though the Vx450w is much less effective and older it sounds way more open and musical. The strong and muscular HX750 makes everything muddy and without snap. Am I just crazy? Ear-Fatique? Any others that have had the same experience? Monitoring: Beyerdynamic DT 880 Pro. - The HX750 shall have lower amounts of ripple and noise according to measurements. (!) Edit: (!!!) I might also get more jitter from my SSD drive according to HD Tune Pro. Could PSU affect Random Acess times on my SSD? Wow. 1. VX450W (PIC) -------------------------------------- 2. HX750W (PIC)
  9. Hi, New here, based in the UK. My old CD player packed up and a friend of mine who is a serious hi-end HiFi enthusiast kindly bought me a Schiit Modi. Since I have so much music on my Macbook now, and have stopped buying CDs, he said it would be a convenient way of listening to my collection. It arrived yesterday, with leads supplied. I plugged the leads into the back of the Modi and my amp (an old Rotel) and plugged the USB lead into the Modi and my Macbook and... Nothing... Zilch... Nada. The power light on the Modi stays off and nothing happens on the Macbook. I spent the morning using the Schiit troubleshooting guide, changed the leads, USB ports, input to amp and still nothing. Any suggestions? Sort of tricky, because I don't want to contact my friend (it seems a little ungenerous since he was kind enough to buy it for me) and i don't know where he bought it. Of course, if I have to, I will, but would rather not. On a relatively new Macbook (OS 10.7.5). Tim
