I've been using balanced power for over 15 years now with my first unit being a Cine-Pro power pro 10 which was really a Furman just rebadged as Cine-Pro. It was a major step up from what I had been using which was an Adcom ACE-15. Much improved bass depth and articulation along with soundstage solidity were its main attributes however it was limited to 10 amps max and I was utilizing 70-80 % of that. I used it for about 3 years and I then upgraded to a PS Audio Power Plant P600 which as many know outputs balanced power. The P600 lasted about 6 years before it died and it was a revelation to say the least at the time and after visiting my local dealer, he mentioned a then new company called Platinum Power which utilizes a 2500VA balanced transformer. I took the PP-1 beast home where it handily out performed the P600 hands down in every audiophile/perfomance attribute you can name! It is fed from a 15 amp dedicated circuit but only drawing about 8 amps max from it so there is more than ample headroom.
I repaired the P600 and dropped it into the HT system where it was happy for about 5 years until it died again. As luck would have it, I was looking thru my local Craigslist and lo and behold a PP-1 was listed for sale for dirt cheap so I snagged it up as soon as I could and again, it improved the whole HT system especially my Plasma display which was surprising given that it had been powered with regenerated power. It too is powered by a 15 amp dedicated circuit and the system draws about 7 amps max.
One of these days I plan on running 20 amp dedicated lines to both the main rig and the HT rig just to remove that small bottleneck even though I am not utilizing anywhere near the 2500VA transformers capacity. Bottom line is I will be using balanced power for the foreseeable future.
As a side note, the new AudioQuest Niagra 7000 with its DBS transformer looks very interesting, I'm going to track one down this weekend at Newport and give it a listen.
