Should Amps be plugged into a power conditioner?

I wouldn't put a conditioner in front of my amps.

Though I do have dedicated lines, as well as a whole house surge protector at the box, and I own my house, so YMMV.

Even though I did not find reduced dynamics with my Everest, I just put together a battery inverter system, and the dynamics, energetics and bass control are on a much different level than when the Everest was plugged into the wall. I still plug everything into the Everest, but the Everest is now plugged into the inverter. A major improvement to my system.. everything about the sound presentation has been improved and I didn’t know that it needed improving.

This was a really illuminating discussion.  I have always had a McIntosh power amp (currently a MC 312) plugged into a Furman Elite 15 power conditioner and never thought much about it.  After reading this discussion, I tried plugging the amp into the wall and it does indeed seem much happier -- and as a result, so am I. Thank you everyone who participated in this discussion.  (Now, I just have to keep an eye out for errant thunderstorms like we had in the Northeast last week).

Congratulations.
 

remember when I did exactly as you. Same result.

Then I put in a direct line and an even bigger improvement. 

If it's a good conditioner then why not? Mine is...and it sounds great.
