  1. This is a good question :) I don't have the answer. You can ask on the forum which "Science" in the name. A guy from Gustard is answering questions there, and can be reached with @gustard. Although you might be informed that they have a strong cultural bias against 10 MHz clocks over there... I can only share my own experience: this DAC offers a good implementation of 10 MHz clock signal, in the sense that the input of such a clock signal really is audible and favorable. Just my 2c and my experience, on my system, with my ears :-)
  2. An interesting review of this DAC: https://soundnews.net/sources/dacs/gustard-x26-pro-dac-review/
  3. Hi Tavy, Thanks for sharing your comments and difficulties. I have not tried the AES/EBU interface myself. Are you using any external clock signal when feeding AES/EBU ? Will try go give it a trial next week and report.
  4. Congratulations to both of you. Hope you will enjoy your new DAC as much as @patatras and myself 😊
  5. Yes. And the SDA-6 too: https://shenzhenaudio.com/products/singxer-sda-6-primary-direct-solution-cchd-957-femtosecond-clock-of-usb-nos-model-dsd512-ak4499-dac-decoder They claim they are having a sale this week.
  6. Antonio, I'm really not a big fan of the solution you are proposing. As has been largely discussed by eminent professionals in this thread, the subject of reclocking or getting a better clock signal that the one provided at the DAC is a difficult subject. The SDA-6 already has excellent clocks at the USB input and doing a better job that these internal oscillators requires a very high level clock, which I am not sure the hat reclocker has. In case you are really sensitive to the benefits of high precision clocking, I would suggest you save your money and buy a good clock in the
  7. Hello Antonio, It's kind of a difficult question, as the answer very much depends on your personal taste. Had I not purchased the SU-2 prior to buying the SDA-6, I would probably not have bought one, because the USB input of the SDA-6 is already very good. Adding the SU-2 gives a little bit more of aeration in the highs. But not to the point that this is a must, like on other DACs which USB input are notoriously bad. And you already have a device which has the reputation of having a good galvanic isolation. So start with the SDA-6 and enjoy :-) Just my 2c
  8. If you allow me to nuance your statement, Leter from Singxer does actually answer emails. It takes time, because it's a small company and the guy is super busy, but in case the matter is of importance, he does answer. To illustrate this, when I received my second SDA-6, the external clock input was not working as expected. When the external clock was locked, the music stopped. This was quite unusual in terms of failure. I had to discuss this with Leter, and he kindly instructed the reseller to change the DAC without further question. I would like to take the opportunity of this narr
  9. Yes you're right. In the SU-2, there does not seem any XMOS chip is involved in the process of USB. It seems all FPGA based. In the SDA-6, an XMOS chip is in charge of the USB interface. Results is quite different IMO.
  10. I noticed that AO3.0 is removing TCP/IP v6 services, which are essential for Diretta (https://www.diretta.link) to operate correctly. You might want to make a note of this in a future version of the user manual and propose a way to reactivate those services through REGEDIT. Thanks
  11. If @Superdad or @JohnSwenson want to have a look at the SDA-6 layout, here is a picture of mine :
  12. Unfortunately not. The limit through USB input is 384k. Through I2S and SU-2 you can attempt 768k. As @patatras noticed on his SDA-6 and as I noticed on the second machine I bought for a secondary setup, DSD 1024 is not guaranteed. It works on my first machine but not on the second one.
  13. Interesting question judging from the results. The implementation in the SDA-6 is quite different, probably more in line with what you would expect (synthetizer). Difficult to judge from the layout as the clock part of the board is under a large "Femtco Clock" cover...
  14. I understood you had decided not to intervene anymore. I am surprised to see your further comment. Your behavior deserves more compassion that anything else. For the purpose of record I do not dislike you. I do not appreciate the way you judge people and things, which is very different. From now on, I will use of my privilege to cancel your contributions here. Thank you for your understanding.
  15. I do not appreciate your ad hominem attack. This is very disrespectful again. I celebrate your decision not to intervene here anymore. Thank you for that.
