Yes...

Since the 7.1.1 firmware update I've not seen the temperature on my D200 go above 41C, and usually the PSU being slightly hotter than the class A amp section too. Anyone else seeing much lower temperatures? I'm interested how they can achieve such a seemingly-massive improvement in thermal management?

Since the update the highest I've seen my 800 units go is 42. And that was after a few hours of loud music and my system is currently running 24/7.

so far 51 is the max. temp for my 800. But currently it's pretty warm in my listening room and I'm using SAM for about 2 weeks. With 7.1 and without SAM 42° was the maximum I have seen. I usually listen with a volume setting between -25 and -15. As soon as the room temp goes down to normal 20° (currently 25 or even more) I guess the temp will always be <50°.

Hi - do you stack your 250 units?

Mine get hottest when I run the fixed input for TV. Thierry tells me that that is effectively a gain of 0bB, i.e. class A amp flat out, is the worst case situation but no problem at all.
With my horns I run -30 to -40 dB gain, with the boxes -25 to -15 dB. I see high 40s with either.
My amps are stacked but the lower unit usually shows the same or slightly lower temps than the top, which is either a reflection on the tolerance of both the temp sensors and the thermal contact to the heat sink or the effect of the DSP thermal mapping.

the temperature issue is interesting to understand in vertical standing... it's important what part of it will be on the top and what on the bottom? if the hot goes up can warm and damage other circuits? ( in the apple laptop a vertical standing can damage it because there is not a good temperature dissipation). someone noted something?

Kenzo,
I have my slave on bottom but it is still not as hot as the master on top (1-2 degr less for the slave). D-amp in slave have some 5 degr less.
I haven't had the chance to down load the latest software so it will be interesting to see if my temps can be lowered as I had temps in the range of 55-62 degr during my normal playing sessions.

No, both are vertically mounted to a wall. This should give the best cooling as warm air can flow up and cool air can follow from the ground. Theoretically...

I appear to be getting lower temps on my 250 since running 7.1.1, has anyone else noticed similar?
