once in a blue moon i'll hear the surround channels gain a few db and when it does it sounds much better, like i've been missing something all this time, then a few seconds later it disappears again. i never noticed that there was anything wrong until this first happened. there is sound coming from the rear speakers but it just seems that when this happens, for a few seconds at a time, i get a huge difference in sound. when it goes away it's almost like i'm listening to just the mains, center, and sub. when i watch DVD movies is seems fine but when i watch regular TV this [censored] happens. just trying to figure out if i should return it to Onecall.
