Tonearms that work well with better Koetsu stone body cartridges

Hi

I have my heart set on buying one of the better stone body Koetsu cartridges. The problem is I’m having a problem finding a tonearm that’s supposed to be a great match. I’ve read that they sound best with higher mass tonearms. The problem is, not every manufacturer will list the effective mass of their tonearms. I am leaning towards the Kuzma 4 point (11”) and the Ikeda 407. Does anyone know the effective mass of the Ikeda 407? If there are any others that work well with the Koetsu’s please let me know. I prefer new, not used. Thank you.

mijostyn,
FWIW, what I hear has a lot of value to me. Also, since my experience is limited to what I have actually heard, other audiophiles opinions of what they have actually heard has way more value to me than that of any number of spreadsheets telling me how something is supposed to sound. 



All the best

Well, when a thread is long enough, you will get recommendations even from ear bleeding combinations :-)

when new, try SAT Arm ( a high price tag betters everything )

Not gonna buy the SAT until I first acquire a Porsche Carrera GT for my garage.

Hi dover

If I may ask, when you heard the Van Den Hul Colibri on the Moerch DP8, Helius Omega & the Kuzma 4point (11”) did you feel one sounded better than the others (based on your preferences)?

You also mentioned that with the Helius Omega “it was so different that you wouldn’t have recognized the cartridge”, was it better or worse? Any opinions are appreciated. Thank you.

Yes.
Originally the owner purchased the Moerch DP8 12" based on reviews and suitability for the medium compliance Colibri. This sounded very quick and quite neutral in balance.

Then he becme interested in the Kuzma 4Point so I installed the 3 arms in sequence in one session. He still owned the Helius as well as the Moerch.

The Colibri in the Helius had a more full bodied midrange than either the Kuzma or the Moerch, however the top end was slightly course and less resolved than the other 2 arms.

After comparing the Moerch/Colibri to the Helius/Colibri I then installed the Kuzma 4Point11 with the Colibri.

The Kuzma 4Point11 with the Colibri was very quick, very dynamic and much more resolving than with the other 2 arms. It was easily the best arm for the Colibri. 

As far as Koetsu's go I have owned a few and indeed the FR64S silver wired with B60 VTA bass that I also own does dig deep and provides real grip on the Koetsu's. However for a general arm I am a big fan of the Kuzma 4Point, it is quick, transparent, and ease of setup and VTA on the fly is hard to beat in my view.
