If you only upgrade one component in HT what is it


Pre Amp, Amp , DVD player?

I am looking to upgrade one component in my home theater. Where will I see the biggest bang for my buck. I have the Mitsubishi 57" Diamond DLP using wire world Silver squared flat HDMI, or Purist Audio Design Component with Ferox as interconnect. I have Sunfire TG II and Cinema Grand, Sony s9000DVP as DVD/CD/SACD, I also picked up a Denon 357 to try 1080p upscaling.

Any thoughts on what will make the best mose noticable Audio/Video change. My system is both my HT and 2 Channel. B&W 804s, HTM3S center each with Synergistic Spec 7. Sunfire sig sub and VR-1 von s rear. All interconnects and cables are maxed for my budget (all Synergistic and Purist Audio)

Thanks

Well a projector wont work in my room, I have considered another sub, but not enough bass has not been the problem. Thanks for your input
I have a Monster HTS 5000 and agree that should be on the list too! any recommendations
Skclarey...sorry

I failed to look at your room before posting...my bad. You have a very nice system, I'll start over now.

1. Room treatments....as many as you can afford.

Your RPTV is too small to be useful for home theater use if you're sitting much over 6' away which would provide a 36 degree subtended field of vision.

In all but the smallest living rooms, two-piece projection is the only affordable way to get a sense of immersion comparable to what you have in the last row of a decent movie theater.

Since "black" can be no darker than the screen is, this will require light control in the form of blackout blinds if you haven't built a cave.
