My $.02. I too think that the WTT is a great and novel design. And I agree with others that a Walker or other high quality motor controller will provide an amazing improvement that you won't believe until you hear it. However, I personally have never been a fan of the WT tonearm. I think it's over-damped and squeezes the life out of at least the cartridges that I've heard on it. If one wanted to mount a different tonearm on the WTT, one's choice might be limited to surface-mount types, but I think it might make for an interesting experiment. BTW, I think that the WTT w/Reference tonearm now retails for ~$10K. Not such a bargain for that much money.
