The SINAD ~117 dB at 5W into 4 ohms itself is excellent but not record breaking as we have AHB2 and LA90D a few dBs higher. It's just the base noise floor.
The stunning part is how it keeps going lower and lower to the knee parts at -120 to -130 dB "top DAC" level, still with very high power even at 2 ohms!
Again this may be all very much inaudible, but this is the best I have ever seen in any class or at any price.
Edit: reminds me of Rimac Nevera performance breaking 23 world records on the same day. Hopefully the module will not cost millions.
Edit 2: like the Truthear Zero Red, I was already expecting the distortion to be low but not THAT low!
Edit 3:
@RandomEar could you please add it to the consolidated graph you created? Thanks!
