The BPT 3.5 Signature Plus has completely transformed my system. I've had/heard lots of power conditioners and this one sounds closest to the ideal of battery power than any I've yet heard with doing the least harm. I cannot yet find any negative side effects of what it does so well. I accidentally plugged my TV and sat rcvr into it around Thankgsiving (football and all) and was blown away by the improvement, especially in HD. Very similar effects in High def and video to what it does in audio: blacker backgrounds, more natural detail, and 3 dimensionality. Just took the sytem to a new level and without question truly a bargain in that it took a very refined system to a new level of refinement.
