Power supply to Amplifier

The best option would be a dedicated line. Other then that just plug it directly into the wall as Zd542 said.

dedicated line if not then I always wanted to try but couldn't afford home regenerated power. In theory at least it sounds good.

If the power supplied by company is really dirty , then why not regenerated power ( from home power plant like P300) which would be much purer ? Why would it not be good for power amp ? Any conflict between oscillator of regenerator and transformers of power amp?

Dedicated line with its own hot, neutral and ground back to the panel. Don't let the electrician share neutrals with some other circuit.

Some people report that the dynamics of the music seem to be compromised when regenerators are used. Others use them successfully. But no, it's not a matter of a conflict between the oscillator and the transformers, or anything else that may be unhealthy for the amplifier.

I don't think there is one right answer that will always be sonically optimal. It depends on the design of the amplifier and on the characteristics of the AC. For example, with a class A amplifier, which draws essentially constant current all of the time, I don't see why a regenerator would compromise dynamics. On the other hand, it does perhaps seem understandable if the amplifier is class AB or class D, where the current draw fluctuates widely with the dynamics of the music.

Personally, I wouldn't want to be without some sort of surge protection between my amp and the wall outlet. I use this Brickwall surge suppressor/line filter, and I've been pleased with the results. My amplifier is class A, and I live in an area that has no nearby industry or commerce that might pollute the AC.
