Having sold many kosher ones from Ricardo and avoiding the clever copies, I used mine on a Gyro with a Breuer 8-Dynamic arm for many years. That arm was hard to obtain and so I had to find alternatives for my customers.
They and I achieved excellent results via:
- Syrinx PU2
- Syrinx PU3
- Sumiko MDC-800 'The Arm'
- Ittok Mk1
At that time I sold lots of Micro Seiki arms (can't remember which ones) and Fidelity Research FR64S and FR64FX. These gave unremarkable results in this specific situation.
Towards the end of the period I achieved very acceptable results with the then new SME/4 but oddly, inferior results via the then SME/5
I never tried this Koetsu wth a un-ipivot. It gave excellent results via the Air Tangent although a bit bass-shy compared to the same cartridge in the Breuer. The various STAX arms, both aluminium and carbon fiber were unusucessful with that cartridge. Hope this helps
