Who uses power conditioning?

I use Alan Maher Designs which in my system consists now of a multitude of various filters, AC duplex and power cords. Have spent many thousands on it since 2010 and to say it makes a "night-and-day" difference does not do it any justice. But plugging everything into filters first is much better than into the wall...there are no sonic drawbacks with it since, like Bybee filters, this is largely quantum-based, no caps or other traditional "parts" that place a much lower limit on how far the noise can be shifted higher into the inaudible range.

Doesn't matter how much current or wattage the amps use, it's all without drawback.

I have had mixed results with power conditioners. I’ve used Monster, PS Audio, and Torus. At one of my homes there seemed to be an improvement, although subtle. At the house I live in now, I can’t really say it has made a noticeable difference. My conclusion, based on my experience: spending big bucks on a power conditioner is not worth it.
YMMV

Chang Lightspeed CLS 709.......about $1300 discounted, from The Cable Company.

Could not be happier........warm, detailed, 3D, expanded soundstage, and does not limit current flow.
Two outlets for mono block amps, two outlets for analog low power, and four for digital.
Much better than other power line filters, and Pure Power AC regenerator that I have used.
One 709 in main stereo system and one 709  in home theater.

Furman 15 Elite PF
just got it

Oh boy:
Shunyata wall outlets to an Audioquest Niagara 5000 with a Shunyata Defender plugged into it. Also plugged in for more connections is a Shunyata MPC.

From there: AQ Tornados to main components and Shunyata Venom HC cables to other components.
