  1. Thanks for the precision :-) Aren't you missing your Ref-10 ?
  2. Singxer SU-2 is the next generation of MC-3+USB, ie with an I2S interface to feed modern DAC with a nicely galvanically isolated and well clocked I2S music flow. Very good product IMO :-) Hope Mutec will be inspired to release one such product soon.
  3. Also, in my experience, the switch and the tx-USB are the most important in the clocking process. I would invite you to test with the sMS-200 not being externally clocked, while the tx-USB and the sNH-10g are. Obviously, its even more important if you have a gear which is involved in the process of producing or transforming the synchronous music flow, like the MC-3+ USB, a Singxer SU-2 or a DAC itself. Bringing the precision of the REF-10 clock to the synchronous music flow gives better results IMHO.
  4. Why would it be the case ? The SOtM gears are fed the clock signal independently of any MC-3+ unit being there AFAIK.
  5. As far as I understand, the SOtM gears will need to detect if there is an external clock signal available when they boot. So to ensure that they are using the REF-10 clock signal, you need to reboot them with the clock signal being sent, ie the cables attached and the output selected on the REF-10.
  6. Hi Jussi, I'm trying to play with NAA on a Windows 10 machine with multiple ethernet adapters. Is there a special instruction to set in the .bat file to instruct NAA to listen to any one of the adapter in particular ? Is there a documentation about available parameters ? Thanks, Pierre
  7. Hi Pavlos, Congratulations on your choice. Happy listening with your new DAC :-)
  8. Interesting to see such equipment on this site :-) Thanks for sharing. This DAC seems to have some very interesting characteristics, ie a NOS mode, which is well suited to operate with HQPlayer, an external clock input and a seemingly nicely designed full discrete output stage. The measurements made by 7audiolab.com (https://www.l7audiolab.com/f/measurements-of-gustard-x26-pro/) only briefly touch the subject of the external clock at the end of the test, showing a nearfield J-Test which compares two different cables when connecting the DAC to the Gustard C-18 10MHz clock. Did yo
  9. I'm on the same page, and very much enjoying the way you have implemented NAA for this purpose. Just thinking about other and complementary options. Thanks anyway. This will give me the opportunity to enjoy other implementations of your software. I'am already very enthusiastic about testing the Linux version. Pretty much less enthusiastic about the Windows flavour, but I will definitely give it a try :-)
  10. This is not an easy one :-) It pretty much depends on what you are most sensitive to. in my own experience, cleaning the electromagnetic noise, which is the function of the SOtM line of product, was improving the clarity, the transparency of the music. On the other side, using MC-3+USB, and later, REF-10, improved the analog presentation of music, the liveliness, the level of details, aso. So what are you missing most ? If you have an SOtM USB card. correctly powered, you are already on the safe side re galvanic isolation. You might benefit from having a REF-10 to have
  11. Thank you. I will start with the K series, and see how much headroom I have given my expectations and if I can move down to the E series in order to operate fanless.
  12. Do you have any experience with the 10th generation E-series CPU (TDP 65W) ?

    HQ Player

    A short return of experience on the Mac Mini M1. I noticed that it was helpful for me to relocate Roon on my NAS, and to dedicate the M1 to HQPlayer. As I have quite heavy convolution, I noticed that this was helping the fluidity of the experience ; now DSD 256 with ASDM7EC is easy, even from 96k or DSD 128 files. The only remaining problem for me is 192k files upsampled to DSD 256 with EC modulators.
  14. Thanks Jussi. It was more about lowering the power usage (80W vs 125W) in order to move to a LPSU if necessary. Any idea about Intel vs Ryzen and Windows Server vs Windows 10 ?
  15. I am considering building a PC (probably with dual boot Windows and Linux) for HQPlayer, to use as a server together with a NAA. When looking at the performances displayed, it looks like may cores are idle. So is there a point to buy an i9 10900K vs i7 10700K ? Would a Xeon with even less cores be an option ? Also, is there a preference for Ryzen compared to Intel ? Which model then ? Finally, what are the minimum specs for a graphic card (I am not playing games) just to offload some processing to the GPU) ? On the French speaking forum, many users are advocating
  16. I guess it will be interesting to read the listening report from @patatras when he finally gets his SDA-6. He still owns another DAC he is very happy with, and has a very good installation with Roon+HQPlayer+Diretta as well as very well trained ears, as he has received a classical music education and taught music himself. Wait and see what he thinks about HQPlayer filters and NOS mode of AK4499 :-)
  17. Hi Jussi, Congrats for the perf of this build. Would you have a typical config (mobo, memory, aso) you would like to share with us ? Thanks in advance :-)
  18. Yes, until you remove the SPSU, which is soldered to the board. You can test like this and finalise the surgery afterwards. I have posted pictures here a long time ago :-) Before: After:
  19. Same experience here. Removing the SPSU and powering my MC-3+ USB with a rail of my Paul Hynes led to a significant improvement. Up to the point where I only needed one device, which I used to transform the asynchronous USB to synchronous SPDIF. Further reclocking did not appear useful to my ears. [EDIT} But I would like to add that a further game changer for me has been the move to HQPlayer, its upsampling to DSD 256 capabilities and the switch to a DAC fed in I2S with a Singxer SU-2 interface, the SU-2 bieng clocked by my REF-10. This is where my Mutec REF-10 SE120 really started
  20. Hi, Have you talked with Pasternack (https://www.pasternack.com) ? They have good RF specialists who might be able to help you find a technically sound solution. I asked them about 50 Ohm and 75 Ohm cables and they were very helpful.
  21. Then I would move to the MC-3+ USB if I were you :-) Add to this that you will enjoy a coherent timing of your system when you have the external clock, as this will allow you to clock the EtherRegen and the MC-3+ USB with the same clock. Be aware that SU-2 requires a 50 Ohm clock input. Both MC-3+ USB and EtherRegen require 75 Ohm clock input.
  22. Yes it is. What is the input of your DAC ? Are you planning to stay away from DSD and I2S inputs in the future ? If you intend to stick to AES/EBU, MC3+ USB probably is an upgrade compared to SU-1. If you plan to move to DSD, at resolutions exceeding DoP/DSD64 which AES/EBU can handle, and would like to enjoy HQPlayer with full functionality, or move to a DAC with an I2S input, a move to SU-2 would be wiser IMHO.
  23. Hi, My experience with D90/SU-2 was hectic. Combined with HQPlayer, this setup was producing large clicks/pops when changing formats or sample rates. This damaged one of my tweeters so I had to send the D90 back. Apart from that, I noticed a presentation of the sound which was vey detailed, but a little bit matt for my taste, as much as the x-Sabre/SU-2 was very detailed but a bit bright for my taste. The SDA-6/SU-2 is right in the middle, just transparent sound-wise. A lot of air and instruments separation too, whether the SDA-6 alone or in connexion to the SU-2. I have a sligh
  24. The discussion with Jussi was related to external 10 MHz clock inputs in general. A measurement of a cheap OCXO at the input of an SU-2 has been posted above. It's not strictly "external" 5V. But a friend of mine opened his SU-2 and applied 5V. Seems easy to do. I do not have any experience with the SU-1. I compared the SU-2 to my MC-3+ USB in AES and I have a preference for the MC-3+ USB. I found it more transparent. I did not notice any lack of transparency of the SU-2 in I2S mode though. For clock applications, there seems to be a concensus that square w
