I already mentioned that the ISO Regen improved the results, so galvanic isolation can block the noise. But changing the software, also changed the noise! So it appears the noise is generated by the computer activity and it travels along the connection. It's activity AND connection, not OR. And you were still willing to state your opinion (in Objective-Fi?) without investigation of the other measurements. And we don't know all the details of Amir's test. Good point. Do we know all those details from your post? (Direct sound, wasapi etc.?) Maybe you didn't read the whole thing at ASR or the other threads on the topic. The point was the ISO Regen lessened the noise, but only with a DAC that is essentially "broken" b/c of improper design. With other DACs it made no difference. Same for other DACs - except for a small minority that are improperly designed, March Audio's results hold. Conclusion: the PC doesn't matter for these measurements, unless you have a DAC that is inherently defective. Archimago did similar testing at his site a while back and got the same results. botrytis, lucretius, skikirkwood and 1 other 4 Main listening (small home office): Main setup: Surge protector +>Isol-8 Mini sub Axis Power Strip/Isolation>QuietPC Low Noise Server>Roon (Audiolense DRC)>Stack Audio Link II>Kii Control>Kii Three (on their own electric circuit) >GIK Room Treatments.
