I've just tried one of Jim's older units. Remarkable! Correction to above: by ALL MEANS use SOUND APPLICATION units for amps as well. They are designed for high current demand. (JIM will confirm this.) I will simply say this - if you have excellent gear; you owe it the "dramatic" level of clean AC that Sound Application provides. I use reference Spectral with reference MIT. I am very impressed with what the Sound Application most 'basic' unit accomplishes. Without question reference level performance.
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
