Hmm,

Zitat:At this point, I lost my appetite for running more tests. Clearly there are design issues here (I suspect in the buffer/amplifier section). Doubtful that the unit was measured to verify any of the specs published (although power rating is close to mine).

Conclusions
It is tempting to go bargain shopping in asian markets for DACs. Prices are lower and features a mile long. Alas, I have been personally burned over and over again, not having found a single performant unit. This is another example of it. The lesson here is to not get excited over formats listed, DAC chips and specs shown. Unless you see real measurements like I am showing, the performance likely won't be there.

Der Topping NX4 DSD geht da aber besser, +20dB bessere Sinad Werte:

Dafür kein APT-X HD Bluetooth, wofür du auch einen passenden Sender brauchst.
