Yes, I have owned some of your "usual suspects". Here are my impressions of the differences between the two.
I started with the (non-suspension) Basis 1400, with a RB300 arm and a Koetsu Black cartridge. It was a very good upper entry level table. Good dynamics and fairly low noise floor. I originally had a Benz Micro Glider II on this table and when I went to the Koetsu Black, and noticed a definite drop in the noise floor.
I then moved on to the (suspension) Basis 2001, with a RB900 arm and the same Koetsu Black cartridge.
Since the arms were similar (the big difference being the upgraded cabling on the RB 900), the biggest difference I noticed in the tables themselves was the dramatically lowered noise floor of the 2001. The background is pretty "black", and therefore, I appreciate the subleties of the music more. In addition, I feel the bass was more extended as well. The treble also seemed like it was more extended, but I think the lowered noise floor may have been accounted for some of that.
My two cents worth anyway.
