Has anyone heard the new Audio Technica AT-OC9X series of cartridges?


Many of you have probably heard that a new series of Audio Technica AT-OC9 cartridges have been released.  Has anyone either bought or heard any of them yet?

Hi and apologies for taking so long to see your question. Yes I am using the stock Technics headshell with my SL-1200GR. It's May, 2020 now and I'm still enjoying the OC9XSL cartridge. It's a great combination. Neutral, detailed and dynamic without ever sounding analytical or sterile. Excellent imaging and soundstaging with Harbeth P3ESR speakers. The turntable and cartridge play music :)
Audiophiles should pay more attention to Audio Technical products in general IMHO. They tend to provide very good sound for good value.

Definitely, they've been doing it for decades, great brand
Sorry to revive an old thread but I'm currently looking at the OC9XSL cartridge for my Sl-1200GR. I noticed AT are doing aluminium headshells specifically for this series of carts in different weights. There's a 13, 15 and 18g option. Which would go best with the cart and Technics arm?
