My 4B-ST runs warm on the top and warmer on the sides as there is little space between the heat sinks and the sides of the cabinet. Never too hot to touch but the sides do get verrrry warm...
My 4B-ST runs Hot
4B-ST owners, does your amp run hot? After an hour or so of listening at moderate levels my amp is so hot on top that I can't keep my hand on it for long. I do not think I am pushing it that hard, but I might be wrong. My speakers are some small floorstanding PMCs (FB-1). Curious if anyone thinks this is normal or might be a problem?
