Rhythmace4218, Both Sound Application models, the XE-12 and the Reference Line Stage (RLS), need a 20 amp connection. I compared both models in my primary and secondary systems and found the RLS to be a significant improvement over the XE-12. The RLS is more effective in cleaning up the AC hash. Consequently, you get better resolution, purer tone, sharper images, bigger soundstage, more musical presentation with reduced glare and smear, and a more involving experience. It has 6 outlets for Digital sources and 6 for analog. By isolating the digital from the rest, you reduce the effect of the digital hash on your analog components.
Sound Application for power amps
I've tried various power conditioners including Shunyata Hydra's and while they offer amazing benefits with digital and preamps, I have never thought that plugging amplifiers into these sounded beneficial. I currently am using my 300 watt SS amp plugged directly into the wall via a Purist Dominus power cord, which is fed by a dedicated line thru an Audio Excellence wall outlet. I have been told by a few members that the one conditioner that actually improves the sound of an amp is the Sound Application products. I would be buying used and would like some comments on this issue and which one to buy. I was also was wondering if I would need to put in a 20 amp wall outlet to accomodate the SA conditioner. Thank you
