Triplanar VII tonearm & Koetsu Jade Platinum cart.

I must interject that I own a Wheaton Triplanar with a Koetsu Urushi. I tried implementing some of Doug's suggestions. I did not remove the anti-skate weight entirely, but I mounted it as close as possible to the shaft, so that it exerted minimal AS force. I also unscrewed the paddle in the damping trough to the point where it was not making contact with the fluid. These two adjustments had a net negative effect. Overall, the sound was hardened and "peaky", and there was perceptible break-up in the right channel. Adding AS force and re-adjusting the damping paddle eliminated these problems and brought back the sublime sound of this combo in my system. I assumed that Doug's findings simply do not apply to the Wheaton cum Koetsu combination. YMMV and all that.

Guess I'll just limp along with what I've got, which sounds wonderful to me. Possibly the Jade has a higher weight than does the Urushi, which might compound any problems related to matching with the Triplanar. I will try out Doug's suggestions on raising the effective mass of the Triplanar, to see if that has a noticeable positive effect. I should emphasize that it required only a little bit of AS force and only a slight dip into the damping trough to tame the problems I initially heard when I tried out Doug's suggestions. Herb Papier (creator of the Triplanar) was a perfectionist, and it was not for nothing that he added the damping trough to later iterations of his tonearm.
