Audio-Technica AT-ART9 phono cartridge

I have limited edition dual-coil Audio-Technica ART-2000 MC (only 1000 made for Japan market 15 years ago, refference line). It's one of my favorite MC cartridge along with much higher priced ZYX Airy 3S and Zyx Premium 4D X.

No problem dealing with 2juki, ebay (buyer protection) always on the buyer side if something wrong with the cartrige, but he sell (for example) ZYX with fake serial numbers, i mean someone replaced the serial numbers makes them looks like it’s factory serials buy they are clearly not!

It’s a tipical grey market dealer’s trick to manipulate with serials, so indeed no support from the official dealers or manufacturers. It’s grey market war... Anyway it’s a strange feeling when you have a cart with fake serial number.
