Any Environment Potentials EP-2050 users out there

I have one hooked up to my breaker box. Easy to install, that's a plus. I can't say I noticed any auditory difference. I'm glad to have the whole house surge protection, but I do note that they don't offer a guarantee like other surge protection systems. That kinda makes me wonder. The other night I think I got some DC on my electrical lines, and I don't think it filters out DC.

I'd like to here other's opinions too.

i have one, and for the whole house surge protection its worth it. its a tough product to A/B (as you have to leave the house to do it!), but when i did the install i will say i noticed less up & down w/ afternoon power...not cured, but better.

power has 2 probs as i understand it:
1) diff noise (between hot & neutral) aka traverse noise aka normal noise---think switching PSs on grid, and incoming trash from the street
2) common noise (between neutral & ground)---think EMI/RFI

any power solution has to treat both. the EP goes after #1, which is IME tougher to treat. power is so so hard to get right. i've the EP2050, Maher CBFs, DIY R-C networks, dedicated lines, Oyaide R1 / WPZ outlets, high $$ power cords, a Weizhi distributor (great product)...and each one made an improvement. and the difference between good power and great power is more valuable than trading up several grand in components.

Thanks for the reply Rhyno. Little confused. I have to admit, most of this is way over my head. I hear what you are saying about diff noise, and EP claims to take care of that. Basically, any garbage created by the appliances in my house as well as any of the garbage coming from my neighbors houses who are on the same transformer will be converted to heat, not shunted to ground, Is this correct?

But EP also claims to take care of EMI/RFI. Are you saying that EP does not attack common-mode noise and therefore, EMI/RFI will be passed through? Would their ep-2750 Ground Filter (http://www.ep2000.com/Templates/ep2750.html) cover this? That is the combo (2050 and 2750) that Doug Joseph at EP has been trying to sell me on.

The reason I am concerned is that I have terrible buzz through speakers, radio stations over speakers, sibilance, etc. that I assuming is at the hand of EMI/RFI. My house is sandwhiched between two radio transmitters, both within a couple miles.

The EP technology seems to be similar to the PS Audio Noise Harvester in that it converts the interference to heat/light rather than shunting it to ground. The difference, as I understand it, is the PS Audio works on a very narrow spectrum, while the EP covers a rather wide spectrum of high frequency noise. Like a giant whole-house Noise Harvester. The theory sounds great. I just wish I knew if it actually worked.
