Pickering XSV-3000 (1976)
A $99.95 moving-magnet cartridge that Pickering built around a brand-new stylus shape, then let the reviewers do the selling.
Overview
Pickering introduced the XSV/3000 in 1976, and the company made no secret of what it thought it had. Its own advertising billed the cartridge as the start of "a new modern high fidelity era" and the first of a new generation of phono cartridges. The ads also reprinted a line attributed to Hirsch-Houck Laboratories of Stereo Review (February 1977), which reportedly said the reviewers could not see how a buyer could do better at any price. That is marketing copy, not an independent verdict. It does show where Pickering aimed the product: the top of the moving-magnet market.
The headline technology was the Stereohedron stylus tip, a shape Pickering described as a spin-off of its research into styli for CD-4 quadraphonic playback. The goal was contact area. The tip has a larger bearing radius than a conventional one, in the manner of Shibata-type styli, and Pickering claimed it delivered the least record wear and longest stylus life then achievable in a stereo cartridge. The company paired it with a high-energy rare-earth magnet, which it said allowed the stylus assembly and tip mass to be miniaturized. A Dustamatic brush was fitted to the front of the assembly. That was a Pickering fixture since 1968, and it damps low-frequency arm resonance and sweeps the groove ahead of the stylus. The V-Guard static neutralizer, present on Pickering cartridges since 1959, rounded out the package.
The numbers, as published in the period press, were ambitious. Audio (November 1976) reported a claimed frequency response of 10 Hz to 35 kHz with channel separation specified at 35 dB at 1 kHz, output quoted at 5.0 mV against a 5.5 cm/sec record velocity, and a price of $99.95. A later British survey in Studio Sound (May 1979) listed the response more conservatively at 10 Hz to 30 kHz, with the same 5 mV output and 35 dB separation, an optimum load of 47kΩ/275pF, a weight of 5.5 grams, and a UK price of £64 with replacement styli at £31.50. The two response figures don't quite agree, which is typical of how specs drifted between markets and printings. Treat the top end as "out to roughly 30-35 kHz depending on whose sheet you read."
The Stereohedron tip was there for tracing. Extended high-frequency response is only useful if the stylus can follow the modulations cut into the groove. Pickering's pitch was that the larger contact patch let the XSV/3000 hold the groove through demanding passages while spreading the load to spare the record. The Studio Sound survey put tracking force at a broad 3 to 11 grams. That looks oddly wide next to the low-mass, high-compliance story Pickering was telling, so set up conservatively rather than taking the top of that range at face value.
The XSV/3000 did not stand alone for long. By the time Pickering ran its "Evolution of Excellence" advertising in Audio (February 1980), the line had grown to include the XSV/4000 and the top-of-the-line XSV/5000. The XSV/5000 combined features of the 3000 and 4000 with response extended to 50,000 Hz. Pickering positioned the original as the critically acclaimed anchor of that family.
It is a high-output moving-magnet cartridge that works into a standard 47kΩ phono input without a step-up, and it has a replaceable stylus, which the moving-coil designs it was marketed against did not offer. Original styli are the weak point. A decades-old Stereohedron tip of unknown hours is a gamble, so budget for a fresh stylus or verify what's fitted before putting it on a prized record. Collectors note the XSV/3000 as the model that introduced the Stereohedron name to the buying public.
