Best Speakers with a DNA-1?

I don't want to hijack the contemporaneous discussion of "Speakers costing range of 2500-3500 per pair" on another thread (question by @spendmoney), but I'm curious to know if any of the answers would have been different if the amp were a McCormack DNA-1 Deluxe instead of the Denon 4311-ci.  I'm using this amp to power a pair of Polk LSIM 707's now, and am contemplating my next move.  If any of the responders to that post would care to weigh in here, I'd appreciate it.
