Amp Power Conditioner or not?


I was moving some equipment around and plugged my amp - MF NuVista M3 w/ Nordost El Dorado cable - directly into the wall for what I thought would be a few minutes. To my surprise it sounds better. More open, smoother, less conjested, more three-dimentional. I think I'm going to leave it that way.

Anyone else have the same experience?

I agree with Tpreaves except I added an isolation transformer (2.4kva on a 15amp dedicated line). Might be overkill but for me it made a very minor difference but for the better so for me it's a keeper.

My Krell Monos are plugged directly into dedicated circuits. Sounds fine to me. Everything else is plugged into an APC Power Conditioner/Battery Back-up.
you will get many different opinions, it is the sort of thing you have to try for yourself

buy used and try it

sell if it does not work
I've been listening to it for about three hours now and the improvement is NOT subtle. Is it possible that the PC was restricting the amount of juice getting to the amp? It just sounds cleaner.

The CDP still sounds better through the conditioner, but the amp sound worlds better without it.
