I wouldn't run the B&W CM10 off an AV receiver and plus your Rotel RX1050 receiver is very old and it's time to upgrade to a new AV receiver if you want to stick with a receiver. Rotel's new current flagship AV receiver the RAP-1580 is phenomenal and I would highly recommend that with your B&W CM10. Other great quality AV receivers to consider are : Arcam AVR850, AVR550, Audio Control Maestro, Marantz SR8012, NAD T787 (recently discontinued I think).
But if you aren't doing surrounds I would highly recommend good quality stereo integrated amp or stereo separates.
