Hi everyone. I have been doing some research and I've read alot of things about PS Audio's power plant AC regenerators. I was wondering if anybody here uses the P300, P500, P1000, or P1200, and if they truly made your dreams come true, or perhaps made only a slight difference. I only became interested because I've noticed that at higher volumes when I play my music, if I walk right up to the horn of my Klipsch RF-7's I can hear a faint static hiss. If I pause my CD then I can hear it better. As I increase the volume, the hiss becomes more and more apparent. Now granted, if I was playing the source at these volumes it would be so loud the HISS would not be audible...but it still bothers me that I have HISS despite using XLR cables between the Halo C2 and A51 and A21 amps; PS Audio power cables; top of the line monster conditioner units (htps 7000 and avs 2000); AND I have no lamps or any other things around that could introduce interference. Is this minimal hiss normal, or is something terribly, terribly wrong?
