  1. Hi Wolfgang, Congrats on your acquisition :) I personally have a preference for the AMSDM7 512+fs and DSD 512 when running this DAC. But I am also very happy with ASDM7EC and DSD 256.
  2. You might want to check this DAC: Apart from a different chip (ESS9038 x2 instead of AK4499), it has a lot of similarities with the SDA-6: - NOS mode to make the best out of software upsampling (HQPlayer for instance) - high precision clock with the capability to synthesise a 10 MHz external clock if desired - full discrete analog output stage with volume control - similar price range
  3. Yes it works with the PLL locked by me. No problem detected.
  4. No, I didn't notice any adverse effect using DoP with the AES/EBU input. For the purpose of record, as I am using an external 10 MHz clock with 75Ohm impedance, I have the switch 8 positioned to "OFF". As this switch is also involved in the PLL adjustment of the AES/EBU input, could you check with this switch to "OFF" too ? A few ideas though, as I was myself a big fan of AES/EBU before switching back to USB when I moved to HQPlayer. 1. AES/EBU is limiting you to file resolutions which are probably not the sweet-spot of this DAC. If you want to enjoy the best of this DAC
  5. I am using HQPlayer to adjust volume
  6. Sorry for the late answer. Been busy trying another DAC of interest (Gustard x26Pro) :-) I reconnected the SDA-6, used my SU-2 to generate an AES/EBU flow from my USB output. In HQPlayer, I chose DoP at 64x44.1k Everything if working well. Is this the test you were looking for ?
  7. 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 :-)
  8. An interesting review of this DAC: https://soundnews.net/sources/dacs/gustard-x26-pro-dac-review/
  9. 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.
  10. Congratulations to both of you. Hope you will enjoy your new DAC as much as @patatras and myself 😊
  11. 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.
  12. 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
  13. 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
  14. 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
  15. 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.
  16. 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
  17. If @Superdad or @JohnSwenson want to have a look at the SDA-6 layout, here is a picture of mine :
  18. 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.
  19. 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...
  20. 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.
  21. 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.
  22. I already have a guardian angel and I do not need a second one. Thanks for trying to use your skills in French to guarantee the alignment of my positions of both fora. I am not sure there is a need for that ! I have a difficulty when someone has no experience and not ever listened to a product or technology and is busy trying to discourage the other ones to make their own experience with this product or technology. When you argued against Diretta saying that this product was just a way to correct for unreliable implementations of USB at DACs ()your own word ar
  23. Not sure what your intention is with this post. I personally have no agenda. I am sharing what I hear and I do not need any backup or explanation. And I am certainly not trying to convince anybody to buy an expensive clock if this is not what they are willing to. I observe that there are a lot of places in this forum where people explain their enjoyment of adding high precision clocks to their setups and especially in connexion with the EtherRegen. I have not observed that you tried to dissuade them to make such kind of stupid decisions if this is you mission. You might want to ext
