It all depends how much are you willing to spend on your hi-def experience?
$500-$1000, $1k-2k, $2k+?

Receiver:
You can get a decent new generation receiver for around $500-1200. Higher price usually mean more features, more inputs and higher power output. But not always! So keep that in mind.

Speakers:
You can always pick-up an All-In-One-Box speaker set.
But these are usually not of the best quality and performance is not on par with a separate speaker setup. By separate I mean speakers that are not crammed into one ready to go package, but purchased in a well thought out process usually in separate boxes LoL. One of the first things people usually complain about in these one-box systems is crappy BASS.
I would personally recommend Definitive, Klipsch, B&W, Paradigm, Canton etc.

Sub:
Subwoofer is going to be very important for all those games and action movies you are going to be playing. It adds extra depth and perception to just about every movie/game/music track. You can go for something cheaper and smaller if you have a small room or the opposite if you have a larger room. There are however products that can work in either situation without making too much of a sacrifice.
Velodyne minivee 10, Sunfire True Sub EQ are very small footprint subs, but perform on par or even better than some of the competition at much larger sizes.

It’s hard to recommend something specific if you don't know much about the budget or room specifics. :confused:
But hope some of this info helps.
Good luck. :)

My PRO 150 delivered Today! Also upgraded existing receiver to 92THX, 94HD blueray, Definitive tower subs, center channel, and two rears. :)

If ya want the absolute best HD-audio experience, it's tough to beat a Denon receiver. Those can get kinda spendy tho (although judging by the TV you just bought, price isn't an issue!)

A good value "budget" receiver would be the Onkyo 605. It supports Dolby TrueHD and DTS-MA, and you can find it online for about $400. Very good deal if you ask me. I would definately buy that myself, and some new speakers, if my neighbors in my new apt weren't so damn fussy about how loud I have my TV :( Oh well, hopefully one day soon I'll be able to buy a house by myself and turn it up as loud as I want! :)
