A year or so back, I had a decision to make.
Here was the deal.

I run 3 Amplifiers and 1 pre-amp on my home theater. I was worried about the power source that these required, how clean it was and if it had any problems.

To make a long story short, I had a few $$ and was considering a Power Center type of device. 

But instead of going with that, I decided that with this much amp'age requirement that I would probably be better off with a dedicated power source.

What this meant to me was an outlet in the wall, that I plugged my Amps and Pre-amps into, that was wired directly to my fuse/breaker box.

So  I had that installed, instead of buying a power conditioner. 

There are no other electrical devices hooked to this source. They have their own direct connect to the  breaker box.

So, I have these powered up, using a surge protector, of course, but now a year or two later, would I benefit from a power conditioner in this scenario or do you think they are probably good enough?
