The RMB-1085 are Class D amps using switching power supplies. I had a friend who owned one briefly and the sound was somewhat boring and lacked involvement. Having 10 channels isn't really needed in your system.
I think you'd be better off buying a new Outlaw 7000x for $999. It uses linear power supply with Class AB amps boards at 7 x 130 watts per channel.
If you were willing to up the amp budget some, I'd look at the Monoprice Monolith amps. You could do the 3x200 for $1249 or 5x200 for $1499 (and then use the receiver for any remaining surround speakers).
