Mattblueg,
Not to harp on this point, but I think you're possibly approaching this from the wrong perspective. If you know you're going to go with McIntosh (not a bad decision, but curious why you it's def. mc gear?) then you should get the amplification section worked out and then deal with the source. Why spend 10000 on speakers and drive them with a rotel HT system? If you're not getting the full sound of your 803s, then you'll be spending a lot of money to get very little improvement. It would seem to make more sense to get the sound of your source/amp right, and then see how the 803s fair. If you're not sure what speaker you want to mate with the mac gear, then you're going to need to play around anyway, so I say wait on the speakers.
