Help diagnose the kind of power treatment needed

Terry,

Yes, I agree the assumption is safe. But I understand the reason some people prefer regeneration, others prefer filtration, others balanced transformers, etc is because the way in which the AC is filthy at different locations varies. I'm trying to determine in which way my power is filthy so I know what to look for as a solution.

Trying at home is not an option for me, or at least not a practical one. I can go ahead a buy something, but I would never know if that unit was the best I could have bought, and getting a second unit would take me about additional 6 months...

Thanks all for the input.

Needless to say I was hoping Al would chime in. Very thoughtful and knowledgeable input, as usual from you.

So it seems unlikely I will get much value out of the analysis/measurement I have in mind. Will check out the cost and see if it's still worth pursuing.

Was wondering if the AC conditioning equipment manufacturers might be able to help. Of course they would give me a biased point of view, and it will be tough getting to the right people, but wouldn't PS Audio / Equi=Tech, Furman, etc know in what situations their products tend to work best? Maybe this reasoning is right, but implementing it might not be feasible.
Which companies do you suggest I contact for this?

From reading the exchange between Al and Mapman that Al linked to, maybe a different approach is asking around here which regeneration/conditioning devices have worked best for others using my pre and amp, and hope the results are repeatable at my place. A very un-professional approach. :-) but maybe that's the best I can hope for now?

Psag, I know Shunyata makes good products, but if my AC had "incomplete" sine waves (like those observed on a clipping amp) then a passive filter would not be able to correct that. In that case a regenerator would make more sense, I think. Too bad I don't know people in my area with power treatment equipment I could try at home.
