This is a thread that draws, as a rule, a plethora of conditioner raps: pro and con, and then, which one to buy, if you want to go that route. I own the Audio Magic Matrix for my analog end and the Stealth Mini Digital for my front end. I can't be without them. Listened to my system a few months back, (when I was selling my, original, Stealth) without any conditioner and my music was missing the lovely things that I, obviously, had taken for granted. Soundstage depth and width, bass and a host of other audio lingo superlatives you hear all the time, which really mean, to me, nothing on paper. Power conditioning depends (the benefits that is) on where you live and what's happening electrically in your area. Electricity is very mystical and behaves differently with all...I love my Audio Magic power conditioners. Find one used, doesn't do it?--sell it for what you paid. You'll keep it. peace, warren
