I just came across what looks like an exciting product, and am now a dealer.
I find that many times we spend thousands on our electronics and the incoming electricity is both dirty and vacilating. I have heard that it can swing from 90 volts to 120volts.
Needless to say this is not the best for our equipment and certainly bad for audio performance.

This product "claims" to eliminate this and the reviews seem to bear this out.
Strangely enough they are in my backyard (Chatsworth, CA) and for those who know names in the industry, are represented by Bob Rappaport, who has been involved in this industry for over 30 years.
So if you even suspect that your power is a little saggy, give this product a serious look.
