Playstation sound & science

Finally I found a working PS one for 10 €.

Sounds very nice, a little soft maybe, but got silky and smooth highs without being unpleasantly warm, good soundstage, rich sound like tube.

So what ?

Asked my analyzer and he told me:

Lots of harmonics, K3 = -39,5 dB as bad as TDA1543 and TDA1540.

Bad noise floor around -50 or -55 dB, don't remember.

But harmonics are evenly distributed and both channels are equal.

Lots of DACs including PCM63 & TDA1541 have different harmonics on left and right channel.
Also depending on your luck, chips can have harmonics that are very dominant.b
