New filter/regenerator

Askat: The PPP is a classic regenerator. The Shunyata and Isoclean are conditioners, and you should know by now my thoughts on those; and I'm not surprised they left you unsatisfied. I am surprised you had the same experience with the PPP though, and so I'd want to know more about what you heard (or didn't hear) your electrical (panel) power, system components, and how you have them all configured before I could comment. You can send me an email. Something here just isn't adding up for me.

Husk: Regardless of one's brand prefrences, using a regenerator should never limit dynamics if operated within their capacity, and provided one isn't so foolish as to stick some kind of conditioning device in the chain because "it was just laying around doing nothing.";-) The EP, PPP, and other regenerators should not limit amplifier dynamics as long as (1) they contain no inductive devices (which they shouldn't) and (2) you are using power cords of adequate gauge (10AWG for amps and DACS, and at least 12 or 14AWG for everything else.)

One ExactPower unit can provide up to 1300W of continuous power http://www.exactpoweraudio.com/products/ep15a/specifications.html
What is total rated power consumption of your amps and subs? (You'll probably never use even a third of it, but I prefer to play it safe ;-) My whole tube amp based system (click on my 'system' link) with every device ON (which I never do in practice) only consumes 525 to 545 watts at 80dB!

Neil. Thanks for the advice. I bought a EP 15A.

Well, I've decided to try teh ep 15a and see how it goes. I have a Richard Gray 400s that I may use in conjunction with it. Will give my report when new system is up and running. Thanks Neil for your help/advice.

Nsgarch, Will the stock PC work or do I need an upgraded PC to go from the Exact Power to the wall.

Husk: I'm sure you realize your equipment consumes quite a bit of power ;-) I don't know how loud you like your music, or how efficient your speakers are, but be careful using one EP and get another if you have to. In mono, your MBL's could (conceivably) draw 5 or 10 amps depending how they're configured; with so much potential current draw (again, depending on your preferences and speakers) you should definitely be using 20A dedicated circuits (at least two) wired with 10AWG (not 12 which is still allowed by code in most areas.) The subs are probably not current hogs (they don't even list their power consumption in the specs) because they employ Class D amps operating over a very narrow frequency range. With those huge amps, you might put one MBL and both subs on EP #1, and the other MBL plus everything else on EP #2. An option for EP #2 would be (as I have done) run an umbilical PC to an ExactPower SP 15A (balanced power unit) and then run everything else (source/front-end stuff) with the SP. But you should provide abundant wall-power regardless.

I would not recommend using the stock Exactpower PC because it's 12AWG and you should be using a 10AWG cord.

Jamesw20: I'll repeat the advice to Husk in my previous post:

provided one isn't so foolish as to stick some kind of conditioning device in the chain because "it was just laying around doing nothing.";-)

At best it would be redundant, and depending what you might plug into it, could cause problems for the ExactPower. You just don't need it. The EP does everything the RG does and more. And the EP does all its power cleaning electronically (rather than passively, with chokes and filters) so it cannot impede amplifier dynamics.

I think a lot of people don't really understand that last point (which is why passive conditioners can ruin amp performance): even smaller amps ~100W can and do draw huge amounts of power way above their rated power consumption. But it's only for nanoseconds. So although it won't burn your house down, or even raise the temperature of your power cord ;-), if that energy transfer is not instantaneous, it will affect the ability of the amp to produce clean, loud, transients. The choke (coils) employed in passive power conditioners, introduce a magnetic lag (inductance) which interferes with the instant transfer of large amounts of power - and why they have such a negative impact on amplifier performance. I guess they're OK for low powered stuff, but if you have a regenerator, you should be all set.
