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?

This Technics SL-1200GR or SL-1500C would be a nice upgrade. It might be more than your budget but you set 'em and forget 'em!

Right, between GR and 1500c I would add new mk7 which is exactly $1000 with warranty, sometimes it cost even less! 

The problem with some audiogon posters is complete lack of knowledge about Technics products and other Japanese Direct Drives, most people brainwashed by belt drive propaganda.     
Ortofon can be expected to claim the cartridge is the most important element. But the best cartridge in the world will sound terrible if the turntable and arm are not well enough engineered to retain the stylus in precisely the correct orientation in the groove.  

People do not use GRAMOPHONES these days, modern turntables are very well engineered and tonearms are nice, even those cheap Rega and Project are good toys. Platter will make far less difference than a cartridge for example. Any modern phonostage can work nicely with MM, even Schiit mani for $100. Better cartridge will make any mediocre system better.  


High end / high fidelity sound is about taking extreme care of the signal start to finish. The straight wire paradigm is used throughout the industry to achieve this. Avoid playing with the signal or making the path longer. If you want to improve the sound of your system then I would concentrate on removing any electronics that does DSP or has tone controls. I would switch back to your Sansui preamp and if that is not a great improvement then invest a couple grand in a used high end preamp. This should significantly improve your system far beyond what a turn table change will do. The preamp is the heart of any good system and is worth investing in. The results will then reflect your other components.

I highly recommend Robert Harley’s book: The Complete Guide to High End Audio to orient you to this wonderful pursuit.
