I do own many Mono carts, some from EMT – beautiful ones with backelite jacket. And from Ortofon, old ones and a new one – the Cadenza.
The Koetsu Coralstone Platinum Mono is an outstanding cartridge defining a special class in Mono scanning. If you try it you will understand the enthusiasm for the dynamics Mono will deliver.

Tang,
I use it in the FR-66s on my double Micro Seiki (SDP) table. Currently my Sonic Lab Ultra Eminent Bc is mounted (see „Two Motors“).
Best
E.
