THE WALL---Why?

Does your dealer sell the PS power plant?

They want to sell you some other line conditioner that they carry IMO!

Contact PS Audio for info on plugging in power amps.

PS Audio suggests plugging into the P10 power regenerator, even with big amplifiers. Give it a try.

My system sounded better when I plugged my amps into outlets on dedicated lines (each amp), rather than plugging the amps into conditioners.
I've tried several and it was the same. for low level components, it is a good idea, not only for conditioning purposes, but to help mitigate ground loop possibilities.
But, I've found that my system sounds better with the amps plugged directly into outlets via dedicated lines.

Yes , Why is it amps and power products tend to not do well together ? Class A , D , AB amps have all sounded worse when pluged into a Torus bit for me . Same result with Furutech receptacles with amps .

I find a dedicated 20 amp line sounds better and considering installation cost of such is generally lower than the cost of a good conditioner it's almost a given.  As to why - I'm no EE but I would suspect a "conditioner" alters the supply so that a good quality amp just passes what it's getting.  After all an amp just modulates the juice from the wall so that it follows the (relatively) tiny input from the preamp...
