SECTION A-A" THRU ELLIPTICAL STYLUS ; CONTACT LINE AT RECORD SECTION "B-B" THRU
STEREOHEDRON STYLUS CONTACT LINE AT RECORD. Conventional elliptical styli have
a relatively limited bearing radius at the contact area with the groove. The
Stereohedron combines the elliptical and Quadrahedron concepts to create a
stylus having a larger bearing contact radius at the area in order to reduce
stylus wear and prolong record life.
What is a Stereohedron stylus tip?
... it is the unique, new development in stylus tip design.
It makes possible a wider, more open, finer sound--because it maximizes stereo tracing capabilities with the slightest, lightest touch a record ever had. It adds to the useful life of each record groove because force is spread over a greater contact area. And that means the least record wear- and longest stylus life -- achievable in these times (with a stereo cartridge).
Buy it? Yes you can in the new Pickering XSV/3000. It's the source of perfection in stereo sound.

TECHNICAL DESCRIPTION
October 29, 1976
The XSV/3000 with STEREOHEDRON TIP.
The Stereohedron diamond is mounted in a thin-wall tubular alloy cantilever for extremely low effective tip mass and optimum coupling to a tiny, yet powerful rare earth permanent magnet.
An unusual suspension design affords very high compliance and highly linear motion for distortionless reproduction of high amplitude low frequency modulation while supplying the precise amount of damping at all frequencies.
Results:
1. An extraordinarily smooth and flat frequency response with uniformly excellent channel separation across the entire audio band.
2. Near perfect transient response for superb definition.
3. Accurate tracing of complex waveforms for low intermodulation distortion.
