Time to upgrade my turntable?

I'm thinking about getting a new turntable to replace my 4 year old Pro-ject Debut Carbon with an acrylic platter and 2M Blue cartridge (with about 600 hours on it). My budget right now is about $1000 but would consider spending a bit more for right turntable. Currently my system consists of a Sansui B-2101 2 amp (200 wpc) powering ADS L1290 speakers (the speakers will be upgraded shortly to ADS L1590's when I find and replace a couple drivers). I am using a Yamaha DSP A1 as the preamp (I like the DSP sound fields that imitate jazz clubs and concert halls). I do have the matching Sansui C-2101 preamp but it is not currently in line.  I also use a DBX 3BX DS impact restorer and expander/compressor. 

I listen to classical music and jazz.

What would you suggest? I might prefer to stay within the Pro-ject line as I could reuse the acrylic platter (if one is not provided with the recommended turntable). Perhaps the debut pro or X1?
