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.

Not that you are going to go out and buy one, but the stone bodies work really well on my Kuzma Airline linear tracker. Yes, the arm has high horizontal but not vertical mass, though according to Franc, the design should not cause undue stress on the cartridge. The arm seems to like a lower compliance cartridge based on my experience using some pretty high end cartridges from the likes of Lyra and Airtight. I’ve had the arm a long time. Not sure if this applies to other linear trackers, including the ET2 and Trans-Fi, which are probably easier to get into financially.
The stone body (I have two) really made the difference in my system-bringing up the bottom end (and of course that famous midrange).
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.


@lewm which Triplaner? I have a 7 mk 2 w alu armtube, I always appreciate your sane contributions.
thx

Wish I could remember but Triplanar v7 sounds right. Cardas internal wiring straight from cartridge to phono inputs.

IKEDA 407 is a descendant of FR64S from the same designer, so probably should work well w Koetsu. Just a guess.

MC, where did I or anyone else mention effective mass or compliance? Whatever you may think of their importance, the fact is that some tonearms mate well with certain cartridges than others. I make no claim to know exactly why that is. It’s trial and error. How do you know that some other tonearm might not outperform your OL, mated w your Koetsu?
