Hey AV55, and welcome. Just out of curiosity, why the M-CR603? I believe the M-CR610 is the current model. Did you find one on Craigslist or similar? Do you have a budget for micro system + speakers?
For micro receiver with a CD player, USB, Wi-Fi, and Internet radio streaming, add this
Denon RCD-N7 to your list for consideration. If you aren't tied to the micro shelf system form factor, you might also consider this
Oppo BDP-103 universal disc player + a
separate amplifier. In addition to being able to play more formats, that Oppo player has Internet radio over wifi (probably with more stations and more reliable connectivity), and can read USB media as well.
For speakers, these
NXG Pro 4.1 satellites can be wall-mounted with some $10 brackets, and afterlife2 really seems to dig them.
For a subwoofer, I think the
HSU Research STF-2 would match well with those NXG satellites and work well in a bedroom, offering good low frequency extension from a smaller 10" sub.
