Problem with D250 Pro after the upgrade

[ogs]

Just a follow-up for the above issue. Devialet was gracious enough to offer me a brand new replacement unit, without my asking for it. The new unit works fine (expectedly). I've gotten an overvoltage fault once, but that is a different animal altogether.

That is very good of Devialet! Now you just have to be patient and wait for the amp to break in...  mine got very hot even if it is placed vertically on the wall. After I'd tightened the four screws on the central part of the bottom cover (just a little, around one turn. These lock the D-amp and squeeze the cooling-pad for better thermal transfer to the copper bottom plate)  and increased the distance between the wall and amp to 20mm temps went down from 62-58-54 to 42-39-46 (DPM off).
