Plugging Amp into Power Conditioner???

It depends on the amp and how much instantaneous current it can draw from your outlet. Some amps need a lot of current while others, perhaps switching amps, need less. I didn't notice any difference when my Bel Canto M300s were plugged into my surge protector. And, some amps, like mine, are very sensitive to power surges and I sleep better knowing they are safe. Its up to you and you can try it both ways.

I am not running anything crazy.... Emotiva amps... but from what I was told the engineer says to not connect through LC.... I have a dedicated Circuit...

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.
