McCormack DNA-1 runs hot

That might be fine for Ayre but heat damages parts like capacitors. I routinely have to rebias McCormack amps back to factory spec. At idle you should have no problem keeping your hands on the heatsinks for 10 secs at least.

100 degrees is only warm, not hot. Normal in my experience with my Rev. A DNA-1.

Thank you guys for your comments.
I should have said warm instead of hot: I can keep my hands on it for a long period (was able to do it for 5 minutes even if it's not comfortable). According to SMc, that's normal, it is just heat coming off of it. But what a difference with the Stratos!
Thanks again.

I had some problems with my 225 that ended up being traceable to a bad IC to the preamp. My problems actually resulted in repairs (a good excuse I used to get an SMc upgrade).

I've tried it with 3 different IC to the preamp and with 2 different speakers, same result. The heat/warm comes mostly from the sides, not really from the top. If the rule is to be able to keep your hands on it for more than 1 minute, so that should be normal and I can leave with that (the sound is fantastic). Surpised to see that this fact doesn't seem to borther other owners... Maybe, I am not difficult...
