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?

Joysjane,
I have the Legacy Convergence, which were rated by Legacy as having the same sensitivity as the Focus. Audio magazine reviewed the Convergence and measured their sensitivity at 92db. Legacy seems to include room gain in their figures. I still love em !! (the speakers). My OCM 500 amplifier runs around 115 degrees with these speakers. At 130 degrees things become to hot to hold your hand on.
