What's my next evolution in the analog venture?

What does $1000-1500 gain me? Are new TT's in that price range going to significantly (subjective I know) step over my Technics? I have approx. 300 records and adding quite frequently to that. I listen to everything from Miles, Norah, George Strait, Phil Collins and anything classic rock (Journey, Triumph, Boston, Etc.)

My current setup consists of:

Technics SL 1700 (original) w/Ortofon om40 cart
MF V-LPS phono
Rotel integrated and cd player
B&W 685's
AntiCable and Signal Cable speaker wire and interconnects
