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.

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?

Don’t know about the stone bodied models, but the FR64S with Ortofon LH9000 headshell (18g) gets more out of my Urushi than any other tonearm ever, to include Triplanar, Reed, and the Kenwood L07J tonearm on my L07D turntable.
