To SAM or not to SAM and DRC

[Jean-Marie]

I tried a lot of music with or without sam and for 70 percent i decided for sam off. I heard over 100 songs in different genres and made a list and deciced for the better SQ.
But i had one big problem: the temperature. So i made another test: I stopped the music, turned off the 250 pro and wait one hour.
I started the 250 without playing music. Sam on, Dpm off, Vol. 0 db. I turned to the Temperature list. I was shocked. In only 2 minutes the temp of the a-amp climbs from 29 to 75 degrees, without any input. D-amp and supply stays about 38 degrees (With dpm on and sam off the a-amp climbs to 43 degrees). I think my upgraded 250 pro has a real problem. Or has any other user a similar observation?

I'm sorry to say this, but yes this looks very suspicious to me. Especially the test you did with no input. The class A shall reply be barely working and therefore there is no good reason for it to get that hot. 

My recommendation would really be to contact Devialet 's support and ask for their opinion.
