AVR for Magnepan 1.7s

I started looking into upgrading my system and decided to try the Magnepan 1.7s and fell in love with them. After listening to them for 3-4 hours at the dealership I'm pretty set on these. Unfortunately this will probably require me to upgrade my AVR (Pioneer elite vsx91). I use my system for both HT (so will be buying the matched center) and stereo audio. In an ideal world I'd power these an integrated amp but I don't have the budget or the space for that. The dealer recommended the Cambridge Audio 650r. I wanted to see if anyone has had experience with it or other AVRs with maggies. Budget for the AVR is ~1500. Any thoughts are really appreciated. Thanks!
