Anyone else regenerating A/C?

Yeah, I should look for some online and here in Tucson (where we have some GREAT used vinyl stores).

All the Nonesuch records I have, I bought new in the 60's -- for some reason I can't remember what they cost.

"Any other subscribers?" Yes, my EP15A powers my whole system, with my preamp and sources being additionally plugged into an API Power Wedge Ultra 116 that follows the EP. This is a balanced isolation transformer unit, not dissimilar from what EP offers only with more individual transformers (six). The PW also allows the user to switch between balanced and unbalanced AC for each outlet individually, and I can vouch for the added benefits of balanced power, to which I have yet to encounter a downside. Power amps sound best plugged straight into the EP (the PW doesn't provide balanced AC to power amps, its transformers are too small for that).

Aside from the sound quality improvement, another way to see the EP at work is when biasing tubes with a digital meter -- the readings are much more stable, both over time as well as second to second, than with the uncorrected power coming from the wall. I've used this combo for close to three years now since I bought the EP, and haven't had a peep of trouble. Whether the Power Plant Premier can match its performance I can't say, I haven't heard one.

P.S. -- Yes, power cords are still just as critical as without power correction, though as you might expect the cord leading from the wall to the EP isn't as big a factor as the ones plugged into components following the EP.

Zaikesman -- you raised an interesting point about biasing tube amps which is always a pain because of fluctuating 120V. I remember I'd bias my amps when the power was highest so the bias wouldn't go over without my knowing it.

About PC's: When I only had two great PC's (a couple of Dominus) I called Jim Aud at Purist to ask him where in my system he felt they'd be most effective (Jim is a real power maven) and he said use one from the wall to the EP and the other from the EP to the amp. I have a third one now which is for the DAC, the third place in a system that requires a great PC IMO.

Everyone's take on that last point won't always be the same, probably because no two systems are the same. For instance, I've found that if I only have one superior power cord to use with my digital separates, it makes the most difference if I use it on the transport. But it makes sense that if someone has only one good power cord period, they should try it first on the central power distributor (if there is one) or preamp or power amp, since in a multi-source system those are the only positions that stand to benefit the entire system regardless of which source is chosen. But in my system, I can't hear the same degree of difference inserting any particular cord between the wall and the EP as I can inserting the same cord between the EP and, say, the power amp. This makes sense to me if the EP is doing the job it's supposed to, but it also makes sense to me that the first position could be more critical in systems whose power distributor/conditioner isn't of the active-correction type.

Sadly(from a financial point of view)the power cord issue is a BIG one,to me.This has been proven,time and time again,by a dear friend(who is obsessed with PC's,and has about 15 grand invested).I went with a PS-Audio Statement from wall to EP,and another from EP to Ultrapure.I added a(fabulous)Harmonic Technology Fantasy AC to my amp,and a Kimber Palladium PK-10 Gold(no filters)to my REL sub.The rest of my cords are an assortment of Electraglide,and JPS-digital on my CD.Though I am aware cords can continue to make a rather big difference,I am simply not going to allow myself to go further.
Neil,the Orpheus fund begins soon!!It will move slower this time,as I now am incredibly happy,and the "V" has very low hrs!Probably summer/fall.Just a point of interest.
More importantly,than any of this technospeak,I got some new KILLER SOFTWARE to enjoy,which is why I am in this hobby in the first place!!
Best to all!
