exactpower ep 15A

I think Dave is right, plus the guys in the old Exactpower plant in Chatsworth CA (MAP is in NJ) are about to be let go I fear. So unless you can fix them yourself, you're out of luck, at least for the time being.

I hope that if I can't get MAP to start making the consumer units again, that maybe they'd be willing to license or sell the patent to someone who will.
.

EP did sell to MAP. The reason (I'm told by MAP) they discontinued the EP15A, SP15 and Ultra Pure units is two-fold in that the manufacturer of the boards (or other parts) they need is no longer in business together with the fact that (for the balanced power units) they have stopped making balanced power devices as they are now reportedly illegal for residential use according to MAP. MAP has come out with new products in some categories for audiophile & studio use for noise suppression & filtering. One of them that looks extremely capable (and the successor to the UltraPure I) is the EP-WSC-15R...

Zephyr, it's true one of the key parts suppliers for the Exactpower audio units went under. However, balanced power is still perfectly legal, and you need only check with Equi=Tech, the original supplier of pro balanced power units, and the first to get UL certification for domestic units.

I'm sure Balanced Power Technologies' units are perfectly legal as well.

In fact both companies are now working together to promote balanced power.

Anyway, MAP's new products under the Exactpower name are quite unremarkable, and if you want a conditioner/filter unit, there are many better ones to choose from -- just don't use them with amplifiers ;-) I'm primarily upset that MAP has apparently turned its back on some brilliant power regeneration technology, and I just wish they'd sell it to someone if they're too shortsighted to realize its potential.

Next time (whenever that is) I have a conversation with MAP's president/owner, Bob Schluter, I'll ask him why he bought the company in the first place -- if he wasn't intending to use it's one truly valuable asset?

When that patent goes public in 15 years or so, look for a whole slew of efficient domestic power regenerators -- and we'll REALLY need them by then! Or perhaps someone will develop an even better solution . One thing is for sure, stone age products like the PS Audio Power Plant Premier which use generic and very inefficient technology, are going to be replaced very quickly now.

Nsgarch: Thanks....I was surprised to hear the bit on balanced power and residential applications from MAP too as companies like BPT, Equitech and Furman all still make great units in this category. BTW, MAP referenced the NEC Article 647.3 on the subject when I talked to them via phone.

I have an EP15A for power regeneration for my front-end equipment and am quite impressed. I was sorry to hear that they discontinued the EP, SP and UltraPure I offerings...

Thanks for the advice...good luck with your conversation with Bob S. at MAP.

Nsgarch: I have been following along on these threads for awhile now and am getting a great education (thank you very much), and it is clearly focusing me onto a balanced power solution - at least for the front end. But, I do have a couple of questions:

1 - Are you aware of any significant differences/benefits to Equitech v BPT v Furman?

2 - Would powering both analogue (eg - pre) and digital (eg CD) devices into, say a 2QR be problematic from the perspective noise generated by the CD?

3 - My amps and subs are near the speakers while the front end equipment is about 10-15 feet away - would you use another balance power unit for these, too?

I have the ability to rewire the entire room with dedicated circuits, which is part of the plan. I had also planned on the EP15A until I just read that support for the unit is no longer...

Thanks.
