New filter/regenerator

You should add the Synergistic Research PowerCell 6 to that list. I've got one and it rocks. Take a look at the most recent issue of The Absolute Sound for their review.

The PowerCell has also been reviewed here on AG as well as 6 Moons and Dagogo. This is a must audition line conditioner.

Looks like Synergistic Research may take some thunder away from the Lessloss Firewall. The build on the SR PowerCell looks stellar. An all acrylic cabinet is great for resonation control and probably looks fantastic.

Jpl208,
Exactly- Synergistic's website states it has three times the resonance cancelling properties of carbon fiber. I don't know what that would sound like, but one things for sure. I have never heard such expansive and musical sound, nor has my system ever presented detail from such a black sonic background. The PowerCell is simply amazing and worth a listen.

Does the EP15A generate much heat, i.e. how much clearance does it need?

Most all other true regenerators create a whole AC power cycle from scratch, using the wall power as "raw material" so to speak. There are inefficiencies in doing it this way which waste electricity and produce a lot of heat.

The patented Exactpower circuit restores ONLY that part of the AC waveform that is distorted, carries noise, etc. So in the worst cases of electric utility sloppiness, that amouts to about 20% of the total AC cycle. So just fixing the 20% that's actually "bad" yields high efficiency since 80% of the power coming out of the wall is passed right through so to speak. The result is VERY cool operation and reduced electric consumption. A minimum of 1" overhead clearance is fine for the EP-15A, and you don't really need to vent their balanced power unit (SP-15A) at all.
