The Perfect Match - The Biotracer Tonearm and Tangential Tracking
The PS-X800 is designed for audiophiles and music lovers who will settle for nothing but the very best reproduction of music from their record collection. Careful attention was given to each detail of the PS-X800 to make it the new standard against which every other turntable will have to be measured.

The tangential Biotracer tonearm
The Sony PS-X800 is the first turntable to combine the advantages of tangetial tracking with the low-frequency performance of a stable tonearm foundation. Like other straight-line tracking turntables, the X800 uses a tonearm mounted on a moving platform. However, unlike any other tangetial arm in the world, the tonearm of the X800 incorporates Sony's innovative Biotracer design.
The Biotracer's automated Motional Feedback (MFB) system constantly senses and corrects for tonearm vibration. For this reason, the arm provides all the advantages of a solid foundation: full-bodied, detailed low frequencies. And you get the reduced distortion, and improved stereo separation associated with tangential tonearms.
the Biotracer tonearm of the PS-X800 is the first design to fulfill the promise of straight-line tracking. Quite clearly, the combination of the Biotracer tonearm and the tangential configuaration results in a joyful musical experiance.
Uni-Motion design for superior precision
He tangential Biotracer arm provides still more benefits. Other straight-line tracking arms require some slight tracking error to keep the arm moving forward. These tonearms are in a constant state of correcting tracking error. In contrast, the PS-X800 incorporates Uni-Motion design. Uni-Motion brings the tonearm slowly towards the center of the record, even when no tracking error is detected. As a result, the tangetntial Biotracer maintains superior groove tangency. Phase differences between the stereo channels are dramatically reduced. This results in a stable stereo image, with outstanding spatial characteristics.
As a final measure of precision, the vertical tonearm bearings, so important to tonearm function, are made to extremely close dimensional tolerances. Situated in Sony's long-span pivot, they provide the final assurance of exquisite performance.
The PS-X800, with its Biotracer tonearm and straight-line tracking displays exceptionally lower distortion, extraordinary stereo separation and greatly improved reproduction of the inner grooves of all records, most important, the Biotracer tonearm is unique in providing the solid, vibration-free tonearm base necessary for superior music reproduction.
