Is a GREAT turntable under $2000 possible???

A GOOD  rig can be had, but not a great one; the cartridge alone will hit for 1 K ; I would say  4K for impressive sound, and that would include the cartridge.

From my experience, and a whole lot of other people a, Rega P-3 is the place to start, and tweak at your convenience; sub platter, tone arm wire, platter, heavy weight for tone arm; these items will make a Rega sing.

A couple MC’s and MM’s would be nice to have regardless.

This is the answer to your question. You have a nice tunrtable, but i have no idea about the "sound" of your system and all those mentioned components, but i know for sure that different cartridges is what each of us should try. Since you already have a modern cartridge, you have to check the vintage classics to understand why that classics is so highly regarded today. For you Technics tonearm you need a mid of high compliance cartridges, definitely not low compliance. The compliance figure must be about 15cu @100Hz (Japanese system) or 30cu @10Hz (Rest of the world). Actually Japanese 15cu (measured at 100Hz) is equal to 30cu (measured at 10Hz in the rest of the world).

Some cartridges that most likely can blow you away are as follows: Victor X-1II, AT-ML170, Stanton SC-100 WOS and probably the Grace F9E (or higher). They are all Moving Magnet and works fine with your arm and phono stage. If you need help to find any of them let me know in PM, i have some spares.  

Recently i have checked Dynavector KARAT 23RS MR on Technics toneam/turntable and i was very impressed! I would recommend KARAT with its short Ruby cantilever for your tonearm/turntable. My JLTi phono stage was nice for this cartridge, loaded at 220 Ohm in my system.

Knoll Brent, what are you trying to tell me?
