It's too bad you need to rush. Because, I know it looks like a lot and it is, but if you could get the receiver and use 7.2 for now.
then put a few bucks away here and there and pick up a second hand amp this summer.
That is a lot of difference, I am not 100% sure it is worth a $1100 difference. However, having owned Denon for years and now Anthem to me, I'd take the Anthem.
Man I can't believe it is that much in the US. That's what it costs here CDN. Usually there are a few hundred less and in USD in the US.

Maybe that's how they making the extra dollars
