Receiver - Agreed, I'd probably start with the Denon, though those receivers sound more similar in level than not. The Sony, I'd probably leave out. Biamping off a receiver is useless.
Speaekrs, also agree - Of the speakers listed, I'd expect the Paradigms to perform best.
Sub is a toss up, have not heard either.
IMO, the Control Ones should be better than the Cantons, but I'm not familiar with those Cantons.
