FPB Series - Hot Running?

I'm sure the FPB series of Krell amps aren't cool running, but how hot do they run? Too hot to touch? Will they heat a medium sized room to uncomfortable levels without extra cooling? I'm specifically asking about the FPB-200 and FPB-300 - no interest in the 600. Thanks, Kirk

Thanks to all who responded. My room is 14x18 and on the interior of the house, so ventilation / air circulation is an issue, and it sounds like one of the FPB (probably any pure class-A amp) would overheat the room. -Kirk

Itsalldark - That's interesting. It runs LESS hot than the KAV-250? That's the amp I have now, so I'm familiar with how hot it runs - definitely uncomfortably warm to the touch. I had assumed that a pure class A amp would run even hotter, but perhaps the plateau biasing keeps it cooler. Thanks, Kirk
