The Marantz is okay, but I crave more power, so I'm wanting to go the seperates route which was at first recommended my many of you fine gentlemen. You live and you learn right, sometimes the hard way. 
So far I've heard, with a XPA-5 combined with a XPA-2, you get 7 channel setup... If thats true, then all I need to decide on is a Pre-Amp hopefully... but I dont know if I'll need an additional XPA-2 to power the subs. I'm not sure how that works for the .1 and .2... I need lots of channels (more than 7) and have to ability to run 2 subs because eveunually I will be wanting a 7.2 setup.
I'm looking for a pre amp that can provide many bells and whistles, sirius being one of them, also a really good supply of surround settings. Wifi access to communicate with windows vista is a plus.
I will be pushing the RF-83's and the RC-64... and will eventually upgrad my side surrounds and surrounds backs as well to the RS-62 and RB-61... I have officially contracted the upgrade bug...
