$2000 Canadian? So that's like $20 US? Only teasing.
In all serious, that's about $1300, right? You could get a great preamp for that price, but your amp would suffer, in my opinion. If you can extend that by a couple hundred dollars you'd be in the price range of the Denon AVR-3803 which is a VERY cool receiver. It also has preouts so it can be used as a pre-amp, which is actually a pretty common use by A/V nuts I've seen due to the huge feature load. In addition to some pretty spectacular digital circuitry and the ability to eliminate video functions to devote all circuits to clean audio, 7.1 capability and DVD-A analog inputs for all 7.1 channels, it also upconverts S-Video and composite to component video, meaning you only need one cable to act as a monitor out to your television (something I wish my 4802 did...)
That way, you can add better amps later once you have the money to do so.
