Ok gonk, I guess this is where I show my ignorance. You said I could use the RR2150 by itself or with the M2200s. Could you explain the advantages I would receive by pairing the RR2150 up with the M2200s? Would it be worth the extra $600-$700 to get the M2200s? Also, being that the RR2150 is analog,is the only drawback of buying it that I won't be able to upgrade to a surround sound system?

Thanks
