Koetsu cartridges - what arms work?

Thanks folks. All this is very helpful.

I used a Koetsu on a Morch UP4 (blue dot armwand) for a while. Worked very well.

I used the combo on three different turntables (HW19, Progressive, Oracle Delphi) and it seemed equally at home on all three.

Fellow enthusiasts;I have found that the Koetsu Black Urushi delivers superb performance in a Goldmund T3b on a Goldmund Studio( meticulously set up). Likewise another Koetsu Black Urushi performs superbly in a Origin Live Conqueror mk3c mounted on a MICHELL Orbe turntable, full plinth version. TF set at 1.92gr in my Goldmund arm/ TF set at 1.94gr in Conqueror arm; preamp CAT Legend. Please note that KOETSU quote a figure of 5 by10-6cm/dyne compliance, presumably a static measurement. Several reviews of Koetsu Urushi cartridges have indicated compliance figures much higher, both horizontal and vertical. You neither want a arm/cartridge resonance at the low frequency end of the audio spectrum either too low or too high, both situations are detrimental to high quality sound reproduction.Arm effective mass is only one factor in achieving compatibility with a particular phono cartridge, in achieving a desired result.

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.
