Ok so I'm on a poor college students budgit and I stroll through the pawn shops once in a while. Yes I know, they DO try torip you off. Anyways I come across this sanyo two channel amp with the diagonal led power output indicator ($100). It says on the back 400w and the leds will light up to four hundered watts. It does sound really good, but I'm worried about the fact that even when the rest of my equipment, (input, pre) are turned off I can hear a slight hiss about 5 inches and closer to the tweeter. Is this a bad sign of things to come, or is it noticably coloring the sound. I'm attracted to the high wattage but not if it's making my music dirty. I have one more day to return it so please post with ANY comments. Thanks guys. (and gals).
