As long as those speakers are suitable for your particular situation, I suspect they're a good choice. PMC speakers are touted by a few folks around here who are real persnickety.
Cons that strike me: Kinda retro. You could simplify by going with a networking, DAC equipped receiver. Reduce the number of components, save by going with a less pricey cd player/transport, and gain more modern connectivity options. (The Marantz cd player may have usb inputs and other functions to address some of this, I really don't know. But I do know that some day I'll be fully 'puter based and no longer spinning shiny silver discs, and suspect you too would want to consider such things.)
Also, you don't need to bi-amp. Bigger amp? Maybe, but he Parasound is no slouch. Keep your speakers' power handling limits if you do actually determine you need more power. Due to the relation of power to spl, you really need to pour it on to get appreciably louder.
Dealer cost is a plus. Never pay retail.
