Best used 5 channel amp for under $3k?

I am looking to upgrade my home theater amp. Currently, I am running Revel Performa speakers (M20s, etc.) with a B&K Ref 50 processor/pre-amp and an assortment of generally inadequate amps.

I am looking for the best used 5 channel amp available in the $2500 ballpark. My use is 60% movie / 40% music. I am considering the Classe CAV-180 and the Bryson 9B-SST. I insist on having balanced XLR inputs. Any thoughts on these two amps or other alternatives in this price range? Thanks.
