ExactPower EP15A

I love my EP15A. I didn't know about the patent deal you mentioned, but it speaks to the unigue circuit design. No other power regenerator offers the features of this unit.

I use an Audio Metallurgy 9AWG power cord. My amp, Martin Logan CLS's and Depth subwoofer are plugged into it -- as well as a 15 foot 10AWG cord to an ExactPower SP15A (balanced power unit) which then powers all the front end stuff. This is the optimum setup, per Brent Jackson at ExactPower.

You can do it without the SP if necessary for $$ reasons, and just plug a high quality power strip (with no breakers or filters) into the EP if you need a few more outlets for the front end stuff.

Both units run very cool. I have a lot of equipment (check my system) and the whole shebang only draws 425 watts or so, with every component powered up.

I agree with Nsgarch. I used to use the PS Audio 600 for my front end gear only. I did a direct comparison of the PS Audio 600 to the EP15A in my system and the EP15A was a definite improvement - more extended on the top end and tighter bass. And, of course, the EP15A runs much cooler. I now use 2 of these units. One for my amps and one for my front end. I think one could handle the entire load, but due to equipment location, it was mroe cost effective to have 2 of them. Nsgarch - did you notice a further improvement in your front end with the addition of the SP15A versus just having the front end gear plugged directly into the Ep15A?

Babybear, re the SP15A balanced power unit:

I considered two EP's for the same reason as you did, but with 1500 watts of available output, you'd have to be running some BIG Krells or tube amps to need more than one EP. And the front end stuff, especially CDT's and DAC's (for some reason) seem to really benefit from balanced power; while big amps, powered electostats and subs don't really.

After I'd had the one EP for a while, with everything plugged into it, (and boy, what a difference that made!) I spoke w/ Brent at Exactpower. I'd already decided to do balanced power for my front end stuff, but I wanted to find out if I should just power the SP from a wall outlet near the front end, or power it from the EP using a long power cord. Brent recommended the latter. And in fact, I think ExactPower has a block diagram of just such a setup on their website now.

And yes, all the front end stuff performed even better with balanced power: blacker background on digital and almost imperceptable noise and hum on phono.

BTW, in case anyone was going to ask, with this kind of arrangement, one doesn't (in fact shouldn't) lift any grounds, and especially not at the balanced power unit! Just plug all the three prong AC plugs right into the outlets.

Exactly my experience as well. Robert Stein from the Cable company, who sold me my Exact Powers, put it this way: "The EP15" is the more important unit, but with the SP15 you´ll get another third in improvement. I think this was as good a description as you can get when talking about sonic improvements.
