I'm setting up my HT and came accross a great deal on a HK AVR 635. I then came accross another great deal on a Rotel 1075 amp. I plan to use the 635 as a pre/pro with the Rotel 1075. I wonder what combo would "best" drive my Monitor Audio RS8 towers:

635/1075
970/1075
970/7075

The MAs are pretty easy to drive but I sure would like to go with a matched set of gear (silly...I know). I would love to hear what you think?

Thanks,
