Nice budget at $2000.00. Maybe consider an integrated amp like a Yamaha A-S1100, Parasound Halo Integrated, or NAD 375BEE. All will have no problem driving your RF-82IIs.

I have used many different amps(Acurus A200, B&K EX4420, Yamaha A-S1000, Parasound 2125, NAD T773, etc.) to drive my RF-63s and all have performed wonderfully. Surprisingly, the Yamaha A-S1000 and it's "90w/ch" was equal to or bettered some of the other amps and their 125 and 200w/ch in my large open family room/kitchen. Very natural sounding and balanced with not too much of anything.
