Which component s to upgrade?


I would like some feed back regarding my system and where I can get the most bang for the back in upgrading my components. What would you change without breaking the bank. I currently have the following:
HK Signature Series 2.0 preamp
Acurus 3 way x 200w for center and rear speakers.
Acurus 2 way x 250w for front.
NHT 2.5 front.
NHT SC1 Center
NHT Rear.
Assume my cables/interconnects are decent/good.
65% Tv and Dvd/35%audio.
I'm getting a new Sony rear projection and the new Samsung DVD player with DVI out soon.
Your suggestions are appreciated.

In what way is your system lacking? That will help with the upgrade route. I have a very similar system and am very pleased, I do have a sub for movies, but everything else is similar to your system.

Don't know your budget but here goes anyway.

Personally, I would look at replacing the preamp. I think this would give you the biggest change in overall sound on all sources and give you a lot more flexibility overall.
