I did visit with Mike at his store. Listened to the 350.8 and it sounds fantastic. I also touched the amp to check heat levels and it's not bad at all. My D'Agostino gets warmer. I would not defer on getting this amp due to heat concerns.
I would not install this amp, or any amp except for class D, in a cabinet without the appropriate space for it to breath and have air circulation.
