The MX-Rs can get quite warm into hot territory but that's driving them for hours on end at very loud volumes; typically they never get more than warm. My experience with the other newer amps (V-5xe and AX-7e) is that they never get more than warm.
Ayre amps - cool running?
Can anybody with experience with Ayre amplification tell me how hot or cool they run? I've had a big Krell, which was very warm when on but no music, and downright hot when actively being used, and I've had big Simaudio monos which were cool when on but no music, and only slightly warm under most conditions.
