Well, I would call Electronics Expo and tell them if they would sell you the Denon 4311 (retail $2100) for $1330 since some guys on AVS Forum has gotten this deal.
If they will sell you for $1330, buy it.
Now you have about $4K budget for your speaker system.
Then call Ascend Audio and see if they would give you 10% off if you buy dual Rythmik FV12 subs (retail $500 each + shipping).
Now you have about $3,000 left.
That's just enough to buy the Philharmonic 1 towers + matching center + matching surround speakers.
What you then have is one heck of an audiophile system for both movies & music.
That Denon 4311 is great for network streaming too.
Oh, and get the $129 Panasonic 220 Blu-ray player for all your Netflix streaming and all kinds of streaming. Of course, it also plays BD, DVD, CD.
If you have Android phone or tablet, there is also Android apps for Denon AVR & Panasonic BD, and most likely your 65" plasma.
Or get some Ascend speakers w/ discounts.
Or get some KEF Q900 + Q600c or Q200c + Q100 surrounds.
