I've had the dual subs running for over a month now, the lpa-1 was only hooked up yesterday, so I can say with certainty that the lpa-1 was the result of the improvements. I'm just amazed by the results i've gotten from the lpa-1 and have been listening to music and watching movies non stop since I hooked it up. That 15% was exactly what I feel was missing. Not to flog the yammie too much, as im sure that something is damaged in it, but there just is no comparison -- my system never sounded this good.
