I went and ran my cable (TV) through my Monster HTS 2600, and the hum is COMPLETLEY GONE! I just saw someone say that fixed theirs that way so I thought what the hell. I used to have the cable go through the Monster, but when we moved into the new house I didn't hook it back up that way. Well it's pretty cool if you ask me, no hum AT ALL!! I put my ear ON the grille and hear nothing, I played a DVD and CD, muted the volume, put my ear ON the grille again, NOTHING!! AHHH!! YES!!!! Just thought I would share my happiness, the wife even said she can't hear it anymore! Now things are EXCELLENT!!!!
