5 ch amp decision- opinions please

In upgrading my HTS I am trying to decide on a new power amplifier-

It has come down to these-

Anthem MCA-5
EAD Powermaster 1000
Parasound HCA 2205A
Sunfire Cinema Grand serII

I use my system about 50/50 music/theater, so musical performance is important.

Any opinions about how these compare? All dealers usually only carry one line, so I haven't had the chance to do a controlled comparison.

Rest of components:

Fronts- Proac Response 1.5s
Center- Proac center channel
Surrounds- JM lab 905
Processer B&K Ref 30 (thinking about going to Anthem AVM20)
