I have a WT classic with the black damped platter and carbon arm and am currently running it with a London Decca Jubilee, which is simply stunning. It has very high output(5mV)sending alot of energy into the arm which I feel it responds too quite well. Decca cartridges don't get along with all tonearms and usually require damping.
The best upgrade i have done was raising both the plinth and the motor of wherever its sitting(I have it wall mounted with a target shelf). I was lucky when I first bought it to have some small and medium adjustable German made cones. The small ones(3)fit under the motor and the medium cones(3 also) fit under the plinth. They must be adjustable. Huge improvement! Later I bought from Marigo Audio Labs some cones especially designed for the WT. This was pre internet, at least for me. I think he's still around. If he still has some I would snag them if you are planning to keep the table. The best thing about the WTT for me has been the ability of the arm to accept so many different cartridges.
