Just a short overview:
I live in downtown Seattle, a very high RF area.
I've used a number of power conditioners over the years; most were passive. Relatively inexpensive models such as PS Audio Quintet and Duet offered benefits with little downside at reasonable cost. I used a PS Audio power plant premier for several years to good effect, although it really is a good match only for low current devices. I augmented it with a Pi Audio RevB on the amps. This was very quiet and effective, I thought, but a bit cumbersome. I came upon the audio magic Eclipse, and that was a step up sonically and convenience-wise, so it replaced both of the above, and provided the deepest, widest soundstage I'd had. At the original price of $3800 it was not exactly "cheap and cheerful", though.
Lately I've been finishing up another round of upgrades to both my main systems, and came into a nice Uberbuss in a trade. Now that I've been listening for a few days, I'm in awe. The soundstage is magnificent (deeeep and wiiiide), and the lack of any grain and grit is a revelation. I heartily recommend this device. It is my opinion this thing is the bargain of the breed.
