McCormack DNA-1 runs hot


I would like to know if someone had any experience with a McCormack DNA-1 amp running hot. I just got one used (updated rev. B) and I am using it with a pair of Magnepans MG-12. It becomes hot when on event without music.

Thanks.

I haven't checked the temperature, but I think it is more than 100 degrees F. Others amp that I used (eg: Odyssey Stratos) didn't run hot at all. I sent an email to McCormack about that and waiting for their comments. Hope this is not a big issue given all the good reviews about this amp.
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'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...

I am not worried anymore after all these comments and really glad to have Steve's point of view. That's make me proud to be a DNA owner. Thanks Steve. Yes, great amp and I will keep it for years...
