you wouldn't belive, but it's actually pretty good. I thought i will be suffering from "oomphness" but not that bad. It's slow on boot (i didn't measure it yet) but once it's in there, it's ok. My only problem right now i that i have to go to the back when turning it on. The opus is acting up, or maybe i wired it wrong. BC when i plug it in it automaticly turns on, even if the is off. I plugged a lead from the back of the stereo, that tells the AMP when to turn on. so i think it should be like whenever i turn on the stereo the amp and the pc turns on, and the same to off. Anoter thing is, that when i shut it down, XP sas it's safe to turn off the pc now, and nuttin happens. any solutions?
