If you've decided on a combo receiver/player you obviously won't need a player connection and since you don't mention TV we won't talk about that connection. So, since your M2s will only be a few feet away, even 18 gauge lampcord will be plenty and you just strip about 1/2 inch on each end and put them through the openings in the binding posts on the receiver and the M2s. If you get that sub when it becomes available you'll need a coaxial cable of adequate length with RCA plugs on each end; should cost about $1 a foot.
