I've been searching for an answer without having to post, as I'm way over my head among audiophiles, but here goes...
I've been suffering for years with a Sharp HTIB. Every time I've gone to upgrade, there was something else I had to spend the money on. Now, finally, the ugly beast has died, and I can replace her with a decent system.
I have shopped around, listening to a lot of different speakers, and for the price the Paradigms to my untrained ears seem hard to beat. They handle Miles as well as Matrix. Now, a source I trust has offered me what seems like some great deals...

I can either get a pair of Paradigm Studio 60 v.2's (slightly used, but by a total audiophile i trust) with a Studio/CC and a new PDR-10 sub for a total of round $1400...

OR

A pair of Paradigm Studio 80 v.1's with matching CC and a PDR-10 for about $150 more...

I've listened to both, and they both sound great. Can anyone help me with a little advice? All things being equal would you choose a v.1 Studio 80 or the smaller but newer v.2 Studio 60? Either way, I'm gonna have to pick up some rear channels as well, and am unsure if I need to go with the same generation.

To add to my confusion, I'm also torn between an entry level 80watt/channel 5.1 Integra Receiver and a mid-level Yamaha 110 watt/channel 7.1 Receiver. The Integra seems more solid, but has less power and none of the bells/whistles of the Yamaha (which has the auto-setup tool with the mic that sounds really helpful).

Any help at all would be really appreciated. I'm suffering in a silent living room and it SUCKS.
