Help with choosing 5 channel amp

Hi, I'm moving my Dynaudio Confidence 1 speakers into my bedroom to set up a home theatre. I'll pick up a SCX Dyanaudio center. For rears, I'll use a wireless Soundcast amp which will drive a couple of Diva Mini Ti's. I need a 5 channel amp. I've been told to look at the Bryston 9B SST2 and the Parasound A51. Anyone have experience with these? At the lower cost end of the scale, someone said to look at the Emotiva XPA-5. My budget, if stretched (and stretched and stretched)could cover a 9B or A51 on Agon. Thanks.
