Audio-Technica AT-20SS Anniversary Edition. I am the original owner of this cartridge. I bought this cartridge new many many years ago, it was the second cartridge I had purchased. It has served me well over the years. The stylus that is in it is not the original and has less than 100 hours on it. Also included is a replacement stylus for it in a factory sealed box, never opened. There is an excellent review here on Audiogon about this excellent and very rare cartridge. I will be moving in the future and will be selling some of my "hi-fi" stuff. I will pay shipping and PayPal fees at my asking price.
