I turned the DPM back on and temps are back around 40. I may tomorrow go back and turn the DPM off just to verify that is the issue - but not letting the temps get too high before abandoning ship. I guess I could also try lowering the headroom in ROON.
I’ve got a 1000 pro feeding Magico S3.
Devialet support has gotten back and suggested DPM has nothing to do with SQ and should be left on. In my brief listen I thought it sounded better but could have been in my head (not ears...)
I always have DPM off, on the 400 it sounded better to me at the top end, I've not properly compared it on the 440.
I just played my system for 5 mins at -19, should be the same output as yours at -22, SAM was 50%, I was playing bass heavy music (warp label remixes), max temp was 42 across all 6 temps.
Are your amps in a cupboard or open to the air?
