Plugging Amp into Power Conditioner???

Some line conditioners limit current; some do not. Really depends on the amp and the line conditioner in my experience.

Elizabeth makes some very valid points.

I have my Emotiva UPA-7 plugged directly into my wall socket which is not on a dedicated line and whenever anyone has watched movies with me they never complained about the sound.

For my 2 channel set up I have a McCormack DNA-1 Deluxe now plugged into a vintage Tice Power Block Power Line Conditioner and to me the music sounds a lot less grainy and lean. I have some improvement in the treble. It is less harsh overall.

I have a big ass 100 watts per channel pure class A Threshold T200, plugged into my TARA Labs AD-10B Power Screen.. I find the sound to be slightly warmer, smoother, and clearer, too... controlled, but, also very slightly compressed, which I think is considered to be loss of dynamics (in the music/recording) by most audiophile's who prefer to plug their power amps directly into the wall.. But, when I plug my T200 directly into the wall, music sounds somewhat out of control and out of focus.
