Well, since no one else has posted, I can give you some alternatives I can lift from WHF Buyers Guide:
CD Players (circa £250)
Cambridge Audio Azur 640C v2
Denon DCD-700AE
NAD C542
Amplifiers (circa £250)
NAD C325BEE
Cambridge Audio Azur 640A v2
Rega Brio 3
Standmount Speakers (circa £380)
Monitor Audio Silver RS1
Quad 11L2
Rega R1
Revolver RW16
Please note, I haven't heard any of the above (except the 685s which I own and think are wonderful!) - I just lifted them from WHF. However, they are all 4 or 5 star rated in WHF.
Hopefully some of the other guys with experience in these can comment on how they all work together. I think the Marantz / Marantz / B&W combination you're suggesting looks pretty good though.
