Good points Retroguy. I recognize the validity of all you say. Just that the power treatment devices I have been around all seemed to take something away from the system. And we audiophiles certainly go out of our way to put that stuff in their. Hmmm. Another audio tradeoff: equipment protection(against surges, spikes, dips, etc.) vs. more pleasure(much of the time). I could make a pretty blue analogy here... That's why I did say that the power regenerators are high on my recommended list. Hopefully offering all the protection you list, without losing some of the magic.
