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

The pinnacle of AT-OC9X series was limited edition ART 2000 released 19 years ago on millenium. Great cartridge! It was made ONLY for Japanese market. 

A friend had an ART 9, which was damaged by his cleaning lady.  He went back to an old OC9 that he found was quite good, much to his surprise.  He found it just as good as his ART 9.  Just different.
Alwho2, thank you for your response on the OC9XSL.  That was the model that I was looking at.  I just didn't want to go into the purchase completely blind, or deaf in this case.

Hi samh. My OC9XSL replaced a Dynavector 20X2L in my system. The OC9XSL is quieter with less surface noise. The tonal balance is more accurate. The channel separation is amazing. The cartridge body is threaded for easy mounting.  

My OC9XSL is on the new Technics SL-1200GR turntable. My phono preamp is a John Curl designed JC3.

I bought the cartridge at the beginning of the summer and It continues to amaze and delight me. Sinatra, Muddy Waters, Gillian Welch, Bill Evans, Bod Dylan... whatever the music the reproduced sound is always natural, balanced, and lifelike. 

When I bought my cartridge there were no hands on reviews and I still can't find one. I gambled and I won.  I'm not a reviewer so I'll leave that for Mike Fremmer. I'll just say that this is not my first audio rodeo and I'm very very pleased with the OC9XSL. 

alwho - I will have an SL-1200G delivered soon and currently looking at a suitable cartridge for the turntable. The OC9XSL is a definite option.
Can you tell me if you are using the stock Technics headshell?
