Arcam FMJ P7 or Parasound Halo A51?

Just took delivery of an Arcam AV8...which is fantastic. Now I'm looking for a multi-channel amp to complement it. Tempting to go with another Arcam product, but I am very much intrigued by the Parasound. I also like that it has balanced inputs (not that I need them right now).

Any thoughts? I appreciate your consideration and time. The world of high-end multi-channel is a new one for me (but I've been well steeped in stereo playback for some years now).

Cheers...
