KC_Mike,

I don't know how long you've been following this board, but it's positively crawling with evidence-obsessed engineers. I do believe line conditioners fall into that "no proof they do anything except in rare circumstances" category of AV gear...much like fancy speaker wire, pricey interconnects, etc.

They've just gotten through chewing up and spitting out somebody extolling the virtues of break-in. Be forewarned, you've just opened up a moderate-sized can of worms...
