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.

Love it when people weigh in with real world listening experience based on a variety of arms and carts they own. Plural not one hit wonders."
What people say they hear does not have much value. First of all with what speakers not to mention the rest of the system? What about his ears? I did a hearing test today on a fellow who complained of tinnitus. He thought his hearing was fine. It was steeply rolled off from 2000 Hz equally in both ears.
 Humans are terrible at describing what the heard. They can tell you immediately that they heard a violin but they can not tell you how the violin sounded. If they have been listening to a well balanced system problems with other systems problems will be obvious when they hear them. They can tell you it is too bright which is really brighter than what they have been listening to which if well balanced means they are right. 
A good tonearm should not have a sound of it's own like the Tri Planar, Schroder CB and Kuzma 4 Point 9. A good cartridge will sound exactly the same in all three arms. I can say the for the Windfeld Ti which I have heard in all three arms on a very well balanced system for what it's worth.

The reality is it doens't.
I have swapped arms many times using the same system, same turntable, same cartridge - all arms have different sonic signatures even the most expensive.
The most recent example was when I set up a Van Den Hul Colibri
on 3 arms in the exact same system - Moerch DP8, Helius Omega, Kuzma 4Point11. Basically I swapped out the arms on the exact same TT/Cartridge in the same system.
Each arm/cartridge sounded noticeable different. In one case - the Helius - it was so different you would not have recognised the cartridge. Just so happens the Helius has an extremely low effective mass relative to the others.
There is some truth to that, and the value varies depending on the listener, but I still think it has more value than people talking about something they haven't heard, and that happens all the time.

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
