One more thing, i found the left side of the unit HOT!! after playing mp3 on 5.0 DD Live for 90 mins.
Is it normal? 
It's quite normal for that model. The JVC's play hot.
If you do a search of F10 under my name (TheChairGuy), you will find a ton of resources in the past couple years on Audio Circle. It's quite nice unit for the money, but it has had it's qualitative (poor construction) challenges.
It both seems to play cooler to the touch, and sounds remarkably better, on significant power conditioning
