For whatever reason, my post was just blocked. But Kal Rubinson (who is a mensch) used a pair of Bel Canto monoblocks for his review of your speakers and was quite pleased. So, please google that, since I can't sent you a link.
They are way UNDER your budget, looking around at the various sales sites.
Interestingly, he did a bit of a shoot out with my speakers (Bower Diamond) in the review and just looking at the size of the woofers are a lot more power hungry. So you would have plenty of room.
Still think the Classe Deltas would be a good choice, but they are slightly OVER budget. But they are probably more than you need, unless you plan on getting a hungrier speaker.
