The Richard Gray units turned my Pass X350 amp into a wimp. I'd go with something else.
Review: Richard Gray 400s AC filter
Category: Accessories
I've read most of the AC filtering reviews, and most of the AC cord reviews. Untill I tried a couple of Nite Power cords i didn't think there was any gain to be had in the AC side of my components. This of course was completly wrong.
After reading about current limiting power conditioners, I decided to try a RGPC 400 on my system. Mentally I likened it to a stiffining cap on a car stereo. i picked up a new 400 at the local stereo place, and added it to my system.
Immediatly I had more brath, and much better resolution in the ribbons. The difference was not as dramatic as the power cords had made, but it was there.
A few weeks later I noticed a used 400 in the classified section, and picked it up. Well, the second one had a much more dramatic effect. I'm not talking about the kind of thing you have to listen hard for, this is a difference you can hear 2 rooms away.
Bass tightened up, and is dramatically faster. all blur is GONE. Ironically, I asked the seller why he was seling, and he claimed that it made his bass boomy. I've never heard Maggies boom ever, but cables and such are often very system dependant.
I'm looking for another one now, I can't wait to see what the 3rd one reveals.
