In the process of upgrading my TV, I ended up getting a new Marantz A/V pre-amp and elected not to hook up rear surrounds for a couple of reasons. One of those reasons was to bi-amp my Vistas off of a Primare amp. Now I want to add back the rears (will upgrade to M-L LX 16s) to go with my M-L center.

So, it looks like I need a 7-channel power amp. Any suggestions that would match the speakers well? Looking in the $1,500 to $2,500 range if possible.
