u/note-p

Hello - I have Denon X4800H which was originally used as 7.1 with Left, Center, Right, Surround Left, Surround Right, Surround Back Left, Surround Back Right

For Atmos currently I am using the Surround Back speakers as Rear Heights and added two front heights. Thinking of going 11 and bring back my Surround Backs and have dedicated rear heights which means I need to power 2 channels via preouts via amp and looking for recommendation of doing this setup.

Any recommendation of decent amp that doesnt break the bank(<$200) or if I should look higher. Plus Should I drife my L& R via amp or use the amp for my rear heights?

Thanks
