Believe in the power: Part II

Since the cheapo powered USB hub still resulted in some noise (possibly caused by ground loop charging), I decided to see if connecting straight to the Seasonic PSU will be better.

Turned out it was much worse than even the mainboard USB power. The highs are greatly reduced, I could even hear a few complete missing notes in one of my test tracks "Shining Stars Bless". Now that I know how power quality affects the highs, I can't believe just how much shit the computer dumps back onto the power supply.

And so, using computer power for audio is a big fat definite no no.

And sadly, there was a D-Amp that uses computer power supply. Imagine how shytty it would sound, especially when class-D amps are switching amps, and having a lousy switch before it would be... disastrous.
