The Acoustic-Signature TA-700 is a full Aluminum design 9 inch tone arm. All the experience we have is built into this magic tonearm. We use Bearings from a well-known Japanese Manufacturer. All bearings are closed versions to ensure no dirt or dust is affecting their lifetime. The arm tube at the TA-700 is made from a pressed Alu bar. This bar is very rigid because of the high pressure applied during manufacturing. Then we drill a hole into it and add the outside contour. This creates a very rigid tube but still having a high damping and resonance poverty and it comes with reasonable low weight. The TA 700 is equipped with a 5 pin connector in the arm shaft. The TA-700 comes with a easy to use height alignment construction.
