it shouldn't be warm my friend.
I deal with them every day, so they get little bit warm after continues playing in the store. How do you have it installed?  is there enough room around it?

I dont really understand what you mean with they shouldent be warm? Do you mean when they are shut off or when they are on? Others that I have asked says that their amps are warm even when they are off and Devialet said that this is normal. They are in a rack on seperate shelves but it is built in to the wall so the cooling could be better.
