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.

compliance is well down the scale of significant factors to the point of irrelevance in a good arm. You may find those who will argue with this but they always seem to relate matching issues they’ve had with other arms and not an Origin Live one.
Of course he would say that - he wants to sell as many arms as he can.
There's a sucker born every minute.

On the other hand, I partially agree in that statement - in my view the quality of the bearings is the most important, particularly with cartridges that put a lot of energy into the arm. 

However, you miss the nuance of what he says - that compliance is less of an issue than many think - he does not claim that compliance has no impact. Origin live arms are medium to upper medium effective mass -  they should work with most cartridges made today. It is more the difficult trackers, very low compliance and very high compliance cartridges that require more careful matching. 

As far as the stone bodied Koetsus ( Onyx Golds ) that I have personally set up the best sound was obtained with FR64S & Sumko MDC800.
Note that those two arms sound different - the FR64S more extended top and bottom end, the MDC800 fuller midrange, less tight in the lower end.

This is my hands on experience, it wasn't a fantasy that everything I own must be the best - which appears to be the rationale for some. 






I own an FR64S and its all that for lower compliance carts. I also use a Groovemaster Ti and it to works a treat for these carts as well although its a bit more restrained.  On my wish list to try is the Glanz and the Schroder broadcast...
"to the point of irrelevance" is close enough to no impact for me.

I miss zero nuance. If anyone is missing nuance it’s the ones still saying compliance is so important. It is- if your arm is crap. If your arm is good then it by definition doesn’t really matter what cartridge you put on it. The arm that is only capable of making certain cartridges sound good is by definition not a good arm. It is a picky arm. It is a specialized arm. It is an arm that can be used with good results only with a very limited selection of cartridges.

That’s the nuance I’m trying to get across.

What gets me, these are all very high end arms and cartridges we are talking about. I could understand if it were budget gear. Cheap arm, compromises must be made. To pay a couple hundred for an arm, and it really only works well with certain carts, fine. A worthy compromise. Totally understandable.

But this is not cheap gear we are talking about here. To pay big money only to get an arm you have to change and buy yet another big money arm just to use an even bigger money cartridge, that is just nuts. That is like, "Thank you sir, may I have another!"
