So with the arrival of some EVS Ultimate Attenuators from Ric Schultz, I've started using my CIA D200's some more. What I'm wondering is, how warm is normal for these amps? When I put my hand on the top of the amp its slightly warm, but the aluminum plate on the back of the amp (which seems to be the primary heatsink) is close to to temperature of the outside of a coffee cup with a hot cup of coffee or tea in it. Is this normal? I haven't used the D200's in a while but I don't recall them being this warm.
