PS3 and my current system - upgrades?

[andymanc120]

Right now I have a Marantz SR-96 Receiver, a Marantz DP870 digital decoder, a Sunfire Mark 2 Subwoofer, KLH 4132's for the front, Boston HD8's for the rear, and a Boston CR1 for the center channel. I have a Samsung LN52A850 LCD television and use my PS3 to watch movies in blu-ray. I use my system 95% for watching movies.

I just moved and I haven't set up my home theater gear yet. Does anyone have advice on what pieces should be upgraded first? In particular, I want the highest quality audio effects. I am most interested in the receiver first, because I want to get it hooked back up, but I don't want to spend all the time just to tear it out in a month.

My priorities:
HDMI 1.3
Highest quality audio support (I may use another player in the future, I want to be as future proof as possible for up and coming audio standards)
I do not have a large place, so I am not concerned with wattage. I want superb sound quality, followed by solid features and reliability.

Budget wise, I am not looking to waste money, but I can see going 1-2k for the receiver, and a similar amount for new speakers.

Thanks in advance for your advice.
