Retail $3,650.  Never used, excellent condition.  The AMG 9W1 tonearm has been developed with a completely new patented principle of engineering. A standard tone arm with horizontal and vertical axles will have bearing play caused by the principle of design. With the 9W1 tonearm we have totally eliminated this play in the horizontal axis by replacing it with two 0.5 mm thick spring steel wires. This also enables a direct acoustic coupling which draws from your record exactly what is truly on it. This principle is also used in the rotor heads of helicopters replacing the standard bearings and eliminating their play. The vertical axle is made of hardened tool steel and precision ground to a backlash-free fit with a needle roller bearing. The axles are maintenance free and never need to be adjusted. The antiskating system is also integrated in the bearing case. In the upper rim of the arm shaft you see a two M 1.5 hexagon socket screws. By loosening them you can move them up and down and adjust the antiskating force. Positioning the screw higher will result in a stronger anti-skate force. All materials we use are stainless steel, tool steel, spring steel, and aircraft quality anodized aluminum. The arm tube locking lever is molded plastic, the coupling attenuation sleeve in the counter weight is Teflon and the insert in the arm tube rest at the lift is made of silicone 

Questions for the seller
It looks like it was used, as the mounting holes for the base and cartridge have clearly been installed and show signs of installation with paint removed. Please correct or clarify.
Here is some background for the arm. I am an AMG dealer and purchased it new 8/21 for personal use. Regarding the question on use, I did set it up on a used Pierre Lurne turntable but was not ultimately able to use it as it had a speed variability issue that was not serviceable. So, I scrapped the whole idea and it sat until now. I'm sure you will find this arm in perfect condition for use as I was the only person who ever touched it and I have 40 years of profession installation experience.
