Your right,but i have hooked up a kt88 and el84 based tube amp to it and it did change the sound of them for the better.I have listened to a couple of power units and of them all i like what balanced power does the best.Just my choice.

thanks

It was mentioned earlier, that RFI is in fact blocked by the equipment transformers, but the line run from power-cord input to transformer might still radiate RFI into the chassis/internals and cause problems, specifically, could cause op-amp oscillation.

Is RFI the major culprit then, that conditioners aim to reduce? If so, why not just put a R/C, or a ferrite, on the line run in question, or even on the power cord, and eliminate the costly conditioner units?

What are the noise frequencies that we are worrying about here (regarding op-amp oscillation risk, etc) - are they in the MHz ranges, or are they down in the kHz ranges?...

I'm quoting my own post questions  , just hoping if anybody (please) has any answers or suggestions?
