Power Conditioners

I have a dedicated 20 amp line to my system and still benefit from balanced power condtioning. There is a BPT FS on Audio Asylum

I really like my TORUS 240v 15a balanced power isolation component.I am running 6 components and 3X 7bssts and a 4b-sst.She's DEAD QUIET.When funds are available will purchase
a 20a version just for the amps.There pricey (3000.00).
There is a review in Sereophile(using a pair of 28 B-ssts)
and there on the BRYSTON SITE.There is lots of reviews ect.

I would recommend Alan Maher's Power Enhancer V. It's a passive unit that works well with any audio equipment. At $275 it's a no brainer.

I went with very recently with a PSAudio Duet Power Center for $299.00. I guess you can call it a passive unit. It filters the A/C power and a surge protector far better than the mass market protectors out there. It also provides four 120VAC outlets. No question there is a large difference in the overall soundstage, detail, and clarity of the music being reproduced. There's an excellent technical video on the Duet at their website psaudio.com. I also recommend folks watch their DVD called "Coal to Coltrane". They send it out free and it's a study on power in general. Very well done by their own staff and includes their President Paul McGowan. Their website is jam packed with well researched technical info on power, power cords, cable, etc. I believe in their products.

Briefly. balanced power is good for both ends. Equitechs website is quite informative with no mumbo jumbo
or magic act.
It is hard science and indisputable.
That said
there are excellent results to be had using complimentary p/c's with(after) the Equitech. And that too is fact.
