But i believe that proper conditioning and good cables can compensate for a lot of the hash from the AC line.
I went that route with Entreq gear. The best power conditioner I’ve ever used, and still use.
And the Ziro Disclosure power cord - mind blowing what a power cord can do, when it addresses RFI/EMI.
Still when I installed the Bakoon DAC into my system, I was blown away at the noise floor and lack of distortion.
I read about the Japanese audiophile who had his own electrical pole installed. Sounded crazy at the time, but not so much anymore.
