I used Tidal and have just moved to Qobuz. Tidal's functionality is far better than Qobuz but the SQ is vice versa, especially with classical music. I can stand by the stupid functionality but not SQ.

I see it conflicts with your previous posts. You said that USB cable does not effect sound.

If the signal cannot be effected, why does cable manufacturer try to isolate electric line from signal line and many armors are applied? I think more jitters can be produced on the worst cable than the good cable. Do you mean the better cable should be used for the poorer quality DAC? I'd like...

The sound signature is the same but the soundstage is different because the better USB cable carries less noise and more exactly signal (I mean the signal does not loss or incorrect). And the better source you have (music server vs PC) or the shorter cable you have, the different is more subtle.

Amazing test and clearly evidence. If someone can't hear the different, he is very lucky and he should feel happiness. If someone can hear the different, sorry to his wallet but he should feel more happiness.

I am very happy with my Wireworld Starlight 7, it is more details than Supra but less bright than Chord Silver Plus. To my ears, the Chord Silver Plus lost something in bass and low-mid too.

Let try Elfidelity USB Booster III + iPower 5V/2A.

Do you use ISO Regen or Intona Industrial fed Singxer Su-1, or music server ? I tried Intona Industrial fed Singxer Su-1 from PC and feel the sound better. I am considering between iGalvanic 3.0 and ISO Regen, I should wait to see both feedback.

How do you feel ? :D

Did you get the ISO Regen standalone or with the UltraCap LPS-1 ? I am considering about ISO Regen vs iGalvanic, certainly with USPCB USB A>B adapter.

You should try Holo Spring level 1, it's the best p/p separated DAC.

I am using Nos11 v2 but I haven't tried M11 v7 yet. I like classical, especially piano, perform on my Nos11, the sound is beautiful.

I got 8 pairs for me and my friends. All of them like this mod :D. These make my HD800 to be the end game headphones until I can buy Utopia :D .

If you only use i2s (HDMI), you can get the old version or used item. But if you use another SPDIF, you should get the Singularity.

You will hear the warmer sound with Nos11 when moving from ESS9018 Dac but after that you can realize the sound on Nos11 is more realistic and comfortable for long listening.

Sorry for my English skill, I mean after turn on Nos 11 about 1 hour. I bought the used Nos 11 fro my friend and ask him sent it to the dealer near his location to replace rj45 by hdmi and update firmware to V2. It took me more than 1 months and the dealer ask me to burn it about 50 hours.

I received my Nos 11 with Hdmi and firmware V2. I am burning it but I realize the sound is less warm and sound stage more opens after running 1 hour.

I'd like to remind you that AGD will charge you again when you update firmware from DSP V7 (M11) to V2 (Nos11).

Welcome on board :)

You can't go wrong with Singxer-SU1 and Hdmi i2s. You may upgrade your DAC/Amp after few months but you will keep SU1 for few years :D

Please careful with SPC cable. I tried the DHC SPC cable (entry level), it sounds great (transparent, detail, air) but more forward and a bit more aggressive than stock cable.

How does it sound?

I asked but Kingwa said that impossible because the DAC chips placed on the same board.
