As noted above, amps that run hot tend to fail sooner, due to the degradation of the capacitors, etc. I have no direct experience with Krell, but am familiar with Classe, and currently own Bryston gear. Bryston amps tend to operate at a moderately warm state, although like any amp they do heat up more when they are driven hard. However, my two Bryston amps have never gotten so hot they are uncomfortable to touch.
Bryston's 20-year unconditional and transferrable warranty sets the standard for the industry, and their customer service is outstanding. They even pay the return shipping charge after the repair is completed.
IMO, their current "SST" line of amps will compete with just about any amp costing up to twice as much, and they hold their resale value very well.
