Koetsu cartridges - what arms work?

Soundbuff, By all reports that I have ever read, the Urushi acts as if it does have a very low compliance in that it "likes" tonearms with high effective mass. For example, many have written in these forums that the Fidelity Research FR64S and especially the FR66S are "made in heaven" for the Koetsu cartridges. Can you quote your sources to the effect that the vertical compliance is higher than the manufacturer's published data? Also, can you say what is the effective mass of the T3b and the Original Live, respectively?

I own an Urushi and have only so far used it in a Triplanar, which is "medium mass" as tonearms go. I plan to try it in a FR64S soon.

Hi Lewm Hi FI News and Record Review. I have owned a FR64s &FR64FX & FR66s many years ago. I used a KOETSU Rosewood in the FR64s many years ago and it certainly performed well in this arm.I would not consider the FR66s ideal for a KOETSU URUSHI or the stone bodied KOETSU's. The Triplanar is a superb tonearm but some users have reported variable results with KOETSU cartridges. As I have stated arm effective mass is only one aspect of compatibility. The Origin Live site has the specs of their arms and other info. Mass loading at the headshell if done carefully is an excellent way of fine tuning if needed. The Koetsu Urushi just loves the Goldmund T3b.Setting up of this arm my specialty. I collated info from Martin Colloms, David Wilson and info from a Goldmund Tech by phone many years ago re set up. The Koetsu also worked beautifully in the LUSTRE GTS801 Arm when properly set up.

I have Koetsu Urushi Blue on Graham Phantom Supreme II 10" arm, and it is beautiful. Very quiet, tracks great and the sound is sublime.
(it is on the new Hanss T-60 TT)
