@neonknight Just look at ALL Ikeda cartridges
here, hope you will find yours.
The J.R. is just OEM for US market, normally overpriced compared to genuine Ikeda for Japanese market.
BTW only cantilever-less design is worth the attention, some of them are very rare, this is what Ikeda-San assembled by himself, new Ikeda cartridges are no longer made by the master (RIP).
I was lucky to buy
Ikeda 9 III on dedicated headshell for my FR64s tonearm with B-60.
And later purchased Ikeda
IT-345 tonearm, it was the old arm, not the new CR-1.
No time to compare those beauties, probably next year.
