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

I can't believe no one else has used any of these 2 amps.



A'gon tends to be mostly about 2 channel listening. You probably want to try a more HT focused forum to get your answers.

Given these are for surround channels and not primary music listening, why not Classdaudio?   They have a good reputation and you could purchase 2 of their 4 channel amps for under $2000.  Then spend the difference to have your HVAC ducting for the room resized or a booster fan so you a comfortable in your room!

I also made the change to class d for the same reasons in my 11.1 Auro-3d / Atmos system . I'm currently running a Marantz AV8805 along with
2  Class D Audio  SDS-470 4 Channel amps and a SDS-400C 2 channel amp , also a Nuprime STA-9 in mono and it's a fantastic combo .
Unfortunately the evil upgrade monster is back , and I been thinking about trying a L/C/R 3 channel amp and ATI , Apollon are on my list.
I would think about 3 & 4 channel combo instead of a single 7 / ch amp , as the front l/c/r are priority as I'm sure you know .   
I like the Apollan AS3600 as it can be used as a true three mono amplifier. This means it can be a 3 mono blocks design if only channels one, three and five are used. In this case each module is in mono mode and full power is available for each channel.
I would like to try the 1200AS2 , but ATI USA made keeps calling my name !
Maybe try a single  Class D Audio SDS-470 4 Channel , I think you will be surprised...worse case use it for the height speakers and you have flexibility for your front mains .

Another choice would be a Sunfire 7201.  7 channels, 200 watts per channel, run dead cool, great sounding and on flea bay NIB for $2100.
