Dwhitt,
I was steering you towards one box solutions. If you are interested in two box systems based on an Oppo disk player, that is a whole other deal.
If you are interested in a receiver/Oppo DV-983H system with AM/FM and subwoofer out - look at these:
Cambridge Audio Azur 540R

Music Hall Audio Maven

NAD C-725BEE

Outlaw Audio 2150

Any of these receivers paired with Oppo's best player would make a righteous combo. With the power provided by the Music Hall and the Outlaw, you could easily drive some greedier speakers. In addition to the B&W CM-1 and the Era Design 4 listed above, I might suggest the Dynaudio Focus 110 as well.

One last suggestion:
a Peachtree Audio Decco or Nova + Oppo 981H set up with digital sound out to the Decco and using the Oppo's very good onboard video processor to your monitor. No AM/FM, but onboard DAC, 50-80W amp, tube preamp, and nice sound for between $800 and $1200 depending on finish and power output. Would drive iPod, computer and all other digital sources. Slick, Slick, Slick.
