Amplifier for Monitor Audio RX 8 system

Greetings: I own a Monitor Audio Silver RX 8 package (5.2 system with two MA subwoofers); currently I do not have a dedicated processor and use Pioneer Elite VSX 53 as my processor. I have a Parasound Halo A21 powering my fronts however would rather have one 5 channel/ 7 channel amp powering all speakers (for space constraints); at some point I would move to a dedicated processor with balanced outputs so the amp I will have must have balanced connections as well. I am looking at a Parasound Halo Amp (A51) or a Cary Audio 7.125 Amp - in case of the Cary Audio I will bi amp the front speakers as it is less powerful than the A51. In your opinion, what would match best with the MA silver speakers? Do you suggest a different amp? Many thanks for your help in advance.

Sincerely ...
