Ideally, LPs should be played with the pickup stylus remaining tangential (ie, at a 90° angle) to the groove—just as the lacquer from which the LP was ultimately stamped was cut in the first place. Over the years, many attempts have been made to accomplish this. Back in 1877, Thomas A. Edison's original machines tangentially tracked his cylinders, but Emil Berliner's invention of the flat disc put an end to cylinders altogether. In the 1950s, a number of companies marketed so-called "tangential" trackers that used dual arms, based on conventional pivoting arrangements, to change the angle at which the headshell was mounted as it moved across the LP side. In 1963, Marantz introduced the SLT-12, which used a plastic pantograph to move the stylus across the record surface. Garrard's Zero 100 pivoting arm controlled its independently pivoting headshell with a bar that extended from the main bearing of the tonearm.

Spiral Groove's new Centroid tonearm ($6000) arrived just a few days before press time, so it would be risky to say anything definitive about it. But I will take that risk: using the system described in my review of the SG2 turntable, this may be the best tonearm I've heard. Its sound is different in ways that will open people's ears, and I predict that it will affect the design of every tonearm from now on. The Centroid's design deserves and will await full coverage in its own review, but here are the basics: It's a fluid-damped unipivot design unlike any other that gives the user fine adjustment of all relevant parameters.

As Chester Rice, co-inventor of the moving-coil loudspeaker, once ruefully observed: "The ancients have stolen our inventions." So often, what is painted as new and innovative turns out to be something someone thought of long before. We have a habit of forgetting, and that applies not only to inventions, but to knowledge of other kinds as well.

Much has happened in the analog world since I reviewed SME's flagship Model 30/2 turntable for the March 2003 Stereophile (footnote 1). Back then, spending $25,000 on a turntable (without tonearm) was an odd extravagance intended only for those seriously committed to the format, and who already owned large LP collections. Although new LPs were being pressed in growing numbers, the resurgence of vinyl was still spotty, and the long-term prognosis for the old medium remained in question.

I can't help wondering: how did the mainstream audio press, cheered Dynaco and Marantz and McIntosh and Quad for switching to transistors a couple of generations ago, greet the first tube-revival products from Audio Research and the like? What was the reaction when moving-coil cartridge technology, considered all but dead by the early 1970s, became the perfectionist hi-fi norm just a few years later? And what would the same people make of the fact that a high-mass, transcription-length pickup arm—with interchangeable pickup heads, no less—is one of the most recommendable phono products of 2008? The mind boggles.

It's now been eight years since a Rega P3 turntable passed through my listening room. While the new P3-24 superficially resembles the P3 (and virtually every other Rega 'table), the company has made some significant changes, including upgrading to the high-quality, low-voltage (24V), electronically adjusted motor used in the more expensive P5, P7, and P9. As in those models, an electronic circuit trims the phase angle of the P3-24's motor coils, thus substantially reducing motor vibrations. In 1998, during a factory tour, a Rega engineer demonstrated the circuit's effectiveness to me. As he adjusted the circuit board's pot, vibrations from the motor dramatically decreased, until it was difficult to tell if the motor was spinning or not. Back then, this "hand-trimmed" motor technology was available only in the P9. The P3-24 uses a less sophisticated version of the same basic idea.

Simon Yorke is an artist, a machinist, an electronics wiz, and a political idealist. He's also an analog enthusiast who melds aesthetic and technical considerations into eye-catching, densely packed, compact record-playing devices that are ruggedly built and functionally elegant. His turntables' smooth, matte-gray, metallic finishes and efficient lines make them among the most visually pleasing ever made.

Visit www.stereophile.com and look at the Vote Results for June 17, 2007: You'll see that when we asked our readers to name the one audio product that's spent the greatest amount of time in their systems, the most common answer by far was the Linn Sondek LP12 turntable (footnote 1). Little wonder that Scotland's most famous record player endures as an object of attention for various and sundry commercial tweaks.

Almost immediately on entering the analog marketplace in 1982, Franc Kuzma, a mechanical engineer based in Slovenia, then part of the former Yugoslavia, established a reputation for manufacturing finely engineered, high-performance products that sold at reasonable prices. Kuzma's early industrial designs, however, while serviceable, looked less than distinguished.

VPI Industries' TNT turntable and JMW Memorial tonearm have evolved through several iterations over the last two decades. Some changes have been large, such as the deletion of the three-pulley subchassis and the introduction of the SDS motor controller. Others have been invisible—a change in bearing or spindle material, for example, or the way the bearing attaches to the plinth. And, as longtime Stereophile readers know, I've been upgrading and evolving along with VPI, most recently reporting on the TNT V-HR turntable (Stereophile, December 2001).

Part New Jersey diner, part Wurlitzer jukebox, with a snakelike tonearm that at certain angles looks vaguely lewd, this boxy, man-sized creation from Australia seems to have been built around its distinctive looks rather than for any functional purpose. Combine that with its sky-high price—itself almost obscene—and the result is apparently the sort of product that envious, cynical, self-loathing audiophiles love to hate, and reviewers love to write about.

The Graham Engineering 1.5 tonearm, originally introduced in 1990, was a thoughtfully executed design that logically addressed all of the basics of good tonearm performance—geometry, resonance control, rigidity, dynamic stability—with effective, sometimes ingenious ideas, while providing exceptional ease and flexibility of setup. Over time, designer Bob Graham came up with ways to significantly improve the 1.5's performance, including the replacement of its brass side weights with heavier ones of tungsten, an improved bearing with a more massive cap, various changes in internal wiring, a far more rigid and better-grounded mounting platform, and a new, sophisticated ceramic armwand. (The original wand had hardly been an afterthought: its heat-bonded, constrained-layer-damped design consisted of an inner tube of stainless steel and an outer tube of aluminum.) The arm's name changed from the 1.5 to the 1.5t (tungsten), then the 1.5t/c (ceramic), and on to the 2.0, 2.1, and 2.2.

The lacquers from which LPs are pressed are cut in a straight line, and that's how the LP groove should be traced. Even when set up perfectly, a pivoted arm describes an arc across the disc surface, maintaining tangency to the groove at only two points on that arc. Yet despite numerous attempts at building and selling linear-tracking tonearms, few remain on the market, and most are fraught with technical problems. Linear-tracking arms can be anything but linear, committing more sins of geometry as they meander across the record surface than do their pivoted brethren.

Turntables are intrinsically cool. Maybe it's that I am of the pre-CD generation, for which the acquisition of one's first really good turntable marked an audiophile's coming of age. Just as turntable technology has progressed to such awe-inspiring pieces as the SME 30/2 and Rockport Technologies Sirius III, less stratospherically priced 'tables now offer levels of performance that, if not revelatory, show why so many audiophiles (including yours truly) continue to love their LPs with something just short of fanaticism.
