I wonder if a battery-inverter setup would give cleaner power for less money? For less than $40K you can buy a couple powerwalls along with a top-rate inverter/charger.
Or, with less insanity, DC powered equipment running from batteries. Which is still pretty insane. A good quality PSU should be able to tolerate quite a lot of noise. And power conditioners are already a thing.
Clean power + $399.99 amplifier > dirty power + $60K amp.
Earlier quoted context omitted.
I bet you some of those dollars went towards the acquisition of some Brilliant Pebbles [0]! [0] http://www.machinadynamica.com/machina31.htm
This must be satire, right?
$100k in equipment, but I bet none of that went to an oscilloscope to actually quantify the problems they are imagining.
Even a bit would make quite a noticeable difference for a few hundred bucks (or less, DIY).
Zero difference would be 'running in cables', and other things they read about on forums.
At what point does it stop being a hobby and turn into mental illness?
Around $5,000. Lots of really good low-hanging-fruit actual improvements and solid equipment in that price range (combined, for the whole system); above that you're just getting crazy, and likely seeing marginal gains you can't actually hear and/or aren't worth the cost for what you (maybe, possibly, unlikely) might be fooled into hearing.

That’s a double-conversion UPS: AC to DC, a small siphon for batteries and control hardware, and then DC to AC out. I imagine an audiophile would say that the sine wave generated by such a setup wouldn’t be smooth enough. They’d want something like a double-rotary converter, so that a spinning generator is making the final sine wave.
In any case, PSRR (https://en.wikipedia.org/wiki/Power_supply_rejection_ratio) is a real, measurable thing.
