I am the original owner of this barely used arm. It was obtained while I was doing some 'table DIY. I am currently using an identical arm on my 'table with a Benz Glider and it sounds pretty amazing. The arm allows for adjustment of every parameter necessary but it takes time and patience to dial-it-in, so I would not recommend this to a first-timer. You really need to have some arm set-up experience, or the willingness to learn as you go, in order to properly set this up. It's not too difficult, just takes some patience.
The arm is a Uni-Pivot design with a silicone damping trough and a carbon fiber arm tube. The wiring is silver plated copper and very high quality. It comes with a DIN to RCA cable that in itself would retail for $100-$150.
Couple notes: The cueing mechanism doesn't work well; you need to lower the lever by hand in order to prevent your cart from crashing down. Also, the trough is now filled with fluid. I would need to empty for shipping and I don't have more fluid so you would need to purchase a small vial, no biggie. The distance from the top of the mounting collar to the bottom of the armtube is 40mm so if you will plinth-mount you would need a really large platter. If mounting on a separate pillar, you can then adjust the height of the table to accomodate. This arm is not for the "azimuth obsessed" due to it's uni-pivot design and the way it can rock. Once you have it dialed in it's fine, and is rock solid while playing.
Mounting hole: 30mm
Effective Length: 230mm
Mounting Distance: 214mm
Effective Mass: don't know, but I think with damping it can vary.
Comes with all the tools, anti-skate mechanism (line and weight) and a really nice bamboo box. Buyer to pay actual shipping cost and any applicable fees. No returns so know how to set-up an arm before buying this. I am willing to help with set-up for local buyer, we can discuss. Thanks
