For example, Nordost Valhalla made no difference over the stock mains lead.
However, Power amps do seem to be slightly affected in some cases by some mains leads, IME. Waldo Pepper;576189 Wrote: > > ... > > As for mains transformer resonances...

I've studied a lot of info on the web about this, and there does seem to be a view that there may be something to investigate here. I happen to have some suitable carbon-film resistors and polyprop caps... When I get time, I'm going to try snubbing my various linear supplies to see if there is any effect.
