Anyone else regenerating A/C?

Clio09: Yes it does. This can be problematic with power amps, which can sound constricted, if clean, plugged into the API. (The power amp outlets of course get only filtration, not isolation transformers. A lower-powered amp I once used didn't suffer this effect with the API, but the higher-power ones I've used since have.) Apparently the filtration doesn't harm sources however, which do sound better additionally plugged into the API than just running them straight out of the EP (and that's true whether or not the balanced AC is selected). I notice that on their website, EP never says that the redundant filtering will cause stuff to sound worse, only that it isn't necessary, so I assume the versions without the filters must be priced lower, enough to make the option attractive.

I am trying to figure out which of the series mode surge supressors will give me the most unconstricted power, can anyone help?
What i have been loosely planning on doing is hooking up an EP15A to a low cost 2-outlet series mode receptacle plugged into a 20 amp wall outlet.
I have been reading about how most or all surge supressors or line conditioners will constrict the power to a noticable degree, however, the specs on this always seem sketchy.
Brick Wall PW2RAUD -- 15A, marketed as "for high power audio applications...specifically designed to handle high current devices...with a masive reactor that will not be stressed or constrict [power]"

Brick Wall PW2R20 -- 20A. Considering that the only thing differentiating the AUD line from 'normal' Brick Walls is duplex isolation (not applicable here) wouldn't this naturally be much better than the PW2RAUD if you have a 20A outlet, although it isn't marketed as being specifically designed to handle high current devices?

SurgeX SA20 -- 20A, seems to have slightly better EMI/RFI filtering (higher "dB" at any given frequency is better, right?). Surgex claims none of their products limit the amout of current available. Surgex states: "In order to get electricity from the generating station to your equipment the power has to flow through copper wire and transformers - A LOT of copper wire! The power companies try to keep the final voltage close to 120V AC but it is usually one or two (or more) volts low or high. The series element inside SurgeX that concerns some people is made from 10 gauge copper wire (a heavier gauge than 15 or 20 amp house wiring). There is less copper wire in a SurgeX than between the local distribution transformer and your equipment. Any slight variation in voltage due to SurgeX will be less than the normal variations caused by power company fluctuations or voltage drops in the copper wiring powering the equipment." Is that a load of bull?

Which of these three do you think would limit the current the least, and would this be something to worry about in the realm of 100wpc stereo + dual class A/B 350w powered woofers? Would using a class D stereo amp help alleviate audible strains on the power supply?

I bought a PS Audio 300 Power Plant here on Audiogon and I'm very happy with it. In fact it is due back to me within a day or two after being modified. I'm expecting it to sound even better now. I have PS Audio power cords from the dedicated line to the plant and to the amp. The most expensvie cord is to the amp. The P-300 might not be the best unit out there of it's kind but it worked so well for me that I have not done one minute of dedicated listening in it's absence. My rig sounds great but the PS Audio took it to another level. Can't wait to get it back.

No one has mentioned APS PurePower?
A reviewer commented that its down to personal choice or more like system synergy or maybe what kind of power your are being suppied with as to what is best for your own system. He noted that one of his fellow reviewers is all for the Hydra 8 (recently upgraded to (V-Ray) and yet another swears by the ExactPower 15A. At the time PS-Audio's PPP was not out as yet.

The P300 has been in my system for four years now, has worked like a champ and can't imagine it not being there. If ever it broke irreparably I would replace it with the newer model.
