Class d for ht.

I know there are class d haters, so no need to reply.  I'm running 9 channel, fronts is 2 ch bat, which is staying on my totem winds. Looking at 7 ch for 4 ch atmos totem ic82,  surround tribe II and center is Martin Logan cinema which will get replaced by totem next year. Receiver is anthem mrx720 and bluesound for music. I thought about monolith 7 ch for 1600.00, but at 93lbs I really dont want to lug it anymore, getting older. Lol.  Also my music/ht room keeps the heat in.  These are my reasons for class d. I have searched every forum.  At the end of this relentless search its come down to nord and apollon nc252 at $2150.00 7 ch or the apollon as4800 at $3200.00 8 ch.  I'm not sure if the as4800 with 1200as2 is worth the extra 1k and I only need 7 ch. But I will drop 1k extra of it's worth it. Room is 14x24x8.  Does anyone out there have any experience with these amps?  3200 really is my top. Still doing room treatment.  Thank you for any and all advice you may have.  It needs to be class d, room is just to hot even with central ac on. In the winter we keep heat off in this room. Center of the house. 

Thanks Pete
