To DPM or not? That is the question.

At the very least  a more consistent running temperature is going to lead to a more consistent sound quality I'd have thought.

I understand your thought process -- although one of Devialet's selling points for the Expert line is "unmeasurable" thermal distortion, which suggests to me that they don't think the amplifier is subject to (any?) thermal effects on sound quality.  Hard to say, since they don't explain exactly what they mean.
