  1. For those who are looking for the newest driver and firmware. https://download.shenzhenaudio.com/Singxer/ I lost the v2.20 & v2.22 firmware from my computer's backup and had to search endlessly for this! You'll need the latest one to play DSD512.
  2. It will take awhile. DAC's are only starting to form fit I²S as of lately. Hopefully I can afford having a masterclock by the time that they do.
  3. No R2R DAC's I know of that has a masterclock input as of yet, but I do know the Auralic Vega G2 has one.
  4. W4SRecovery reclocks and although it is an improvement, it does not offer galvanic isolation which can improve the sound further. Optical Design is cool but in applied audio science especially in your area of usage, it is not optimal. Anything over 5M length is a struggle and personally I would stick to a regular USB cable that has isolated power/data and properly filtered. This is my subjective opinion, although on paper is it holds true. The improvements that you're hearing is mainly from the computer noise being cut out from the use of an optical connection but that doesn't mean that the jitter isn't affected. If you one day switch over to a full galvanic isolated solution, you will find that the non-optical route will sound better.
  5. I find an improvement from using the ISO REGEN or iGalvanic 3.0 before the Singxer SU-1. What you should be using is a USB regeneration device with galvanic isolation. You should not be using an optical design cable as that increases jitter. This is why fiber optic is not used over Ethernet cables in regards to connecting to network audio adapters. Anyways, I found a photo from awhile back when I started improving my transport with the iUSB, iLink, and iPurifier with a customized USB cable I made. Thought I'd share. If I recall, the Singxer SU-1 made more of an improvement than these three products combined.
  6. I'm also a firm believer that Fidelizer helps lol. I have yet to buy the pro version though. Did it work for you?
  7. Improving the transportation of digital data leads to a very strange but addictive audible changes. It smooths out sound but in a good way. It's as though what your ears pick up becomes less grainy. The overall stereo image is more stabilized and that's probably due to more accurate timing. Because everything comes more precise, my listening tends to accept more than it rejects and in that sense, things like treble becomes less bright or ringing, bass sounds more punchy, and mid range easier to focus on. It's surely important in the rendering of how music notes play to the listener. Sometimes regardless of whether or not we are trying, a lot comes down to the initial sound we hear, spacial cues, micro-details, and how they decay. Because of having less jitter, things begin sounding a lot more uniform and thus pleasant. As vital as it is to improve on things like headphones, speakers, or digital to analog converter.. I now find transport equally as important. My conclusion now is that everything matters. All from how the signal leaves the computer to upon arrival at the DAC. The sound quality will benefit from the use of isolated circuits and superior clocks.
  8. Thanks @elan120 for supplying me with an adapter board for the Crystek CCHD-575 24.000MHz oscillator. Also shout outs to Alex for his clock donation and help in furthering the upgrade venture for this here Singxer SU-1. Unfortunately my upgrade path ends here.. Soon I will be purchasing a sMS-200Ultra and txUSBUltra so I can use it's sCLK-EX clock module to replace every clock within my audio chain. These two clock modules have a total of 8 total outputs when combined. 3 of them are used by the devices themselves, leaving 5 leftover outputs. With that said, the remaining 5 outputs will be connected to the computer's motherboard (system clock), JCAT NET Card's (Ethernet clock), Network Switch (Ethernet clock) , sMS-200Ultra (Ethernet/USB clock), txUSBUltra (USB clock), and Singxer SU-1 (USB/I²S clock). Later down the line I'll add either a SOtM OCX10 or Mutec REF10 (master clock) to feed the two clock modules with a reference level clock signal. This in turn will increase the performance of these frequency synthesizers and ultimately the sound quality. I'm also waiting for a R2R DAC to release that will have a masterclock input option so I can use up more of these masterclock outputs. Knowing that the entire audio chain is run by superior clocks with a master-mind behind it all brings a calm to my heart... and ears! Regards, Tim
  9. Some interesting things taken from his blog. Apparently version 2.0 has 45/49MHz oscillators instead of 22/24MHz. NDK adapter boards is sold on his site.. I already do this, but for those who don't, I recommend BNC, RCA, and XLR cover caps. Here's how mine looks: And as always, I still recommend using the industrial USB connectors. it has 3x better grip force. And lastly if you do NOT use HDMI then this might be worthwhile: (HDMI noise protection caps)
  10. @Quasar Interesting stuff. I can understand and appreciate the convenience of a single box music server. That's quite a lot of devices under one hood though. Just glad there isn't a transformer in there as that would be defeating. Make sure to isolate it as best as you can. @rafa I haven't ever used soldering paste on it, only fluxing so it can flow better but never seems to get sucked out onto the soldering wick enough so I'll give it a second try before concluding that it doesn't work for me.
  11. Thanks for the input Roberto. @elan120 told me that the from his conversations with SOtM is that at least two of the same frequency/voltage destination points can share one sCLK-EX output. The sMS-200Ultra utilizes two of these four clocks. (1) 25MHz for the sMS-200Ultra's Ethernet input (1) 24MHz for the sMS-200Ultra's USB output (1) Not Used (1) Not Used The question that arises is that IF what Kevin said is correct, then that means the same 25MHz clock that is used for the sMS-200Ultra can be tapped into and used for other locations such as a network switch or Ethernet output clock located on a computer motherboard or from an Ethernet output card like the JCAT Net Card FEMTO. The same logic can be applied for the 24MHz clock and be used in conjunction with the Singxer SU-1's USB input clock. This leaves two other outputs that can be programmed for something more worthwhile. Some worthwhile things (1) 22.579MHz & 24.576MHz clock within the Singxer SU-1. (1) **MHz (depends on motherboard) system clock on the motherboard By doing this, a full clock solution can be had, BUT ONLY if each output from the sCLK-EX can support more than 1 designation at a time. For the Ethernet areas we'll need a total of 3 locations (Ethernet Output, Network Switch, and Ethernet Input). For the USB areas we'll need a total of 2 locations (USB output and USB input). The others can easily use one output with two set frequencies. The real question is whether or not using various locations can degrade the overall phase noise of the frequency clock synthesizer. The second question is how much power does each output have and whether or not that would be enough for tapping more than 1 location. Third question is how strong of a signal does it make for it to tapped into multiple times. I don't know much about circuitry as some would think, but I do know the Mutec REF10 has an oven controlled oscillator (OCXO) that has a clock distribution and amplification circuits that supports up to eight outputs with virtually no losses, so even if this is slightly different, I have high hopes. I'm waiting on a reply from SOtM. And for anyone wanting to go further in the clock upgrade territory, they can get their sMS-200Ultra made with a masterclock input option which can in turn can be used with master reference clocks. A reference clock affects your audio system by giving it an ultra-precise external clock signal to increase the quality of the re-clocking process which in turn affects the sound quality of the entire system. Everything else stays the same so the reference clock is not the "master" of the system in the traditional sense of dictating or changing sample rates. (source: https://www.computeraudiophile.com/forums/topic/31857-mutec-ref-10-masterclock/?do=findComment&comment=673676 Hope I clarified some things for you. After all these thoughts I've decided to get a Mutec REF10 or SOtM OCX-10 after I get this sCLK-EX thing up and running with the required RF cables connected.
  12. @rafa Solder wick aren't good so I stopped using them a long time ago. I recommend the SOLDAPULLT 017. Since I don't like blue I use the low static version (017LS). Cheaper solder suckers available on ebay or other websites do not perform as good. As for the XMOS's oscillator, I have the Crystek CCHD-575 in hand thanks to UpTone Audio. Shout outs to Alex ( @Superdad) for being so helpful in further developments of the Singxer SU-1. I am waiting on carrier boards from @elan120. Thanks to his help I'll be able to solder the oscillator on easier, however at this point I'm thinking about doing a complete setup change.. Talking with him has convinced me to replace my UlltraRendu with a sMS-200Ultra to utilize the sCLK-EX clock board that is built into it. The clock board has a total of 4 outputs. 2/4 of them already have 24MHz and 25MHz programmed into them. The 24MHz is used for the USB output. The 25MHz is used for the Ethernet Input. I plan to have the preprogrammed 24MHz connected to the Singxer SU-1's USB input oscillator. I plan to have the preprogrammed 25MHz connected to the NetGear GS105's Ethernet Input/Output Oscillator. I plan to have the preprogrammed 25MHz connected to the JCAT Net Card Femto's Ethernet Output Oscillator. This leaves me with 1 extra output to use on the motherboards system clock. By the way, these are not clocks but frequency synthesizers. This plan can only work if I can connect each synthesizer to at least 3 locations (due to requiring three 25MHz). Kevin tells me he's talked with SOtM and they said you can connect them in parallel but at the moment it's only 2 confirmed locations. If I cannot do 3 locations I will sacrifice the motherboard's system clock upgrade and make a second output of 25MHz as I feel that would be of more importance. How much better are these synthesizers compared to crystal oscillators? I'm not sure. All I know is that I will be saving money going with this route. It will take more labor to have RF (radio frequency) cables installed leading to each location as well as having to drill holes through these devices to make room for SMB connectors, but I feel it will be worthwhile. Also if the sMS-200Ultra (or txUSBUltra) is bought with a masterclock option, you can drop in a rubidium clock like a Mutec REF10 in the future or stay with SOtM for the sCLK-OCX10. The master clock will then synchronize with the lesser clocks and produce a pure sine wave analog output at tighter tolerances with lower phase noise which is suppose to sound even better. Personally.. I don't plan to use the masterclock option as I cannot justify spending $2000-3000 on rubidium clock so I will not have my unit installed with one. That money would probably go towards a good DAC first but If I can free up some funds it will surely be in the books. Here is my plan: Output 2 will either have the frequency required for the motherboard's system clock or be programmed with another 25MHz if I cannot use a single output for more than two locations.. @Quasar I like the idea but why did you use a backwards type A male connector? Are you planning to use the SIngxer SU-1 in the same chassis as your DAC? If that's the case then make sure there is enough isolation. Also please note that soldering on a connector like that will do things to it's impedance.
  13. Here you go baby girl. https://www.mouser.com/new/kycon/kycon-high-retention-usb/ It holds onto the USB cable three times better. I really like it. Best way to remove it and not damage surround areas is by covering areas around solder points with aluminum foil tape and using a controlled heatgun with controlled nozzles. My nozzles didn't come in time so I just used Met-Cal station and slowly inched it up slowly by pulling on various sides while flowing the solder joints. The only way to pull it up at the center is by using a big enough blob of solder to heat all four pins at the same time.
  14. Never mind. I just noticed you have the LT3045 going into the Neutrino.
  15. Interesting modifications. Would be great to see it all assembled with the wires shortened. The wires leading to the NewClassD is probably the most susceptible in terms of possible degradation. And why is your LT3045 soldered to the 24.576 if you are using the Neutrino on the 22.579? I find it hard to understand why you chose to remove the 101μH inductor while keeping the other two voltage regulators beside it. You're not really upgrading much if you leave those there.. You're simply adding another regulator into the mix and all that does is silence some incoming voltage from the USB input. The noisy 1.0V and 3.3V voltage regulator is still in place.. Also why are you using a bypass capacitor at the output of the LT3045? What good does that do? I found all the voltage regulator upgrades to offer similar sound benefits. It's hard to distinguish which one was subtly more since I did all of them at the same time. It's intriguing that you say the clock upgrade was what improved the sound quality the most since I am still waiting on the NDK NZ2520's to arrive so that has made me a little more excited. I will have my XMOS's 24.000 replaced with a Crystek CCHD-575 soon. Photos will be posted as soon as I finish. I'm not too sure if this will offer much improvement but it would be quite nice to match the input oscillator with the output oscillator within my UltraRendu (also CCHD-575).
