The Thales tonearm was mounted on the new Audiostone Pythagoras turntable. The Pythagoras was designed by Micha Huber, the same person who designed the Thales tonearm. The Pythagoras is a turntable built into a multi-shelved rack. The platter and shelves of the Pythagoras are made of granite. Granite, as a rule, rings when struck. Thus, it is usually not a good choice of material for turntable bases or platters. However, the granite on the Pythagoras is very well damped. As a demonstration, while one of my LPs was playing on the turntable, Micha rapped his knuckles sharply on the spinning LP three times. Each time there was a brief, dull thunk, but no ringing. Note to Turntable Designers: If you are going to do this demo, please have your own LP playing. While my LP did not appear to suffer any damaged from the bouncing stylus, my heart rate just about doubled. The Pythagoras is belt driven using a synchronous motor. At startup an optical sensor measures the platter's speed and the power supply adjusts to set the exact speed. Once the speed is set, there are no further adjustments. This eliminates any hunting-seeking while the LP is playing. For a full rundown on all of the features of the Pythagoras go to www.audiostone.com.
