To DPM or not? That is the question.

[Delija]

Without DPM, I've managed once to overheat my 220 Pro Companion, which was below Master - stacked. After 5-6 hours of listening supply temp went to 72°C (the case was VERY hot) and at first right channel (Companion) started to sound distorted and finally it went silent. I've turned on DPM and separated Master from Companion with the "shelf" made of glass - after that, max supply temp is never above 58-59°C - 4-5°C higher than Master.

So - don't use stacked configuration. It's not good for Devialet.
