So here's my 2 cents FWIW, when I was putting together my home theater, I had an electrician put in 4 20 amp duplexes, and plugged my amps into separate duplexes from the digital components. Sounded good to me but nothing to compare it to.
Then I got talked into buying an EQUI=TECH 3RQ and I plugged just my digital components into it. Left the amps plugged direct into the wall. And didn't really notice a difference one way or the other.
Then the owner of the Company, Marty Glasband, a brilliant scientist (may he rest in peace) told me to plug everything into the Equitech for it to work properly so I did, and wow definitely a discernable audible favorable difference - sound was cleaner, crisp as i describe it and a much lower noise floor. No hiss at all. No negative impact on dynamics that I could tell. Everything was tigher if that's the right adjective and especially on the all important center channel -- a nice very noticeable improvement in intelligible dialogue.
That was 2011 and the Equitech is still there today in all its glory, never an issue, never powered down - the longest time I've owned a piece of HT equipment. My recco- do the research and buy an Equitech. You won't be disappointed.
