The xpa-1's would certainly do the trick and sound great doing it. They happen to be on sale for the rest of today anyways as well. I have an XPA-5 that I use for my surrounds now, but I had it driving a pair of Thiel 3.6's as well as a pair pf Magnepan 1.6qr's just to test it out. It does a great job on both.
