Koetsu cartridges - what arms work?

I have used a Koetsu for most of my audiophile life. I still have a Rosewood Pro IV, the last great cartridge from the old man Sugano.

I have used it on many different arms over the years, although not the Graham/Triplaner/insert name of stupidly expensive arm here.  I even bought a Koetsu arm thinking that would be the ultimate. It was the worst. My final solution for this cartridge will be controversial, and disliked by many.

The arm: Linn.

I may be the only person on earth that uses a Linn arm on a non-Linn table. I bought a used ITTOK just to try it out. The Koetsu LOVES this arm! It loved it so much, I bought an EKOS, as it is the ultimate ITTOK.



 

jsl57, that's an interesting response. Actually, I can easily believe it to be true! The Ekos is an arm that I think does well with slightly heavier cartridges and I think tends to be quite able in the bass, which would seem to jive well with Koetsu's. I wonder how the Ekos SE would fare?

I had a Classic Red and a RSP on the Da Vinci Grandezza arm. It worked great. I also had the Classic on a Linn Lp12 with Ekos arm and it worked very well also.

I have the new VPI prime scout. 
JMW 9 unipivot arm. Sounds sublime. 

Does anyone know if this is technically a match? 

Why not take an empirical approach, begin with a low mass arm, and measure the cartridge/arm resonant frequency, and add mass to the arm as needed until you hit the optimal range of 9Hz to 10Hz?
