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.
What I wrote in 2003 of the Model 30/2's build quality and fit'n'finish is also true of the 20/12: "The machining quality of the proprietary setup tools and the smoothness and unfailing certainty with which the various locking screws rotate in their threaded sockets—not to mention the feel of the unlocking mechanisms—enhanced my confidence that the buyer's money will be well spent. The 30/2 is an heirloom product meant to be enjoyed and passed down from generation to generation."
No-nonsense engineering
Because playing records is all about turning mechanical into electrical energy…
Another issue worth considering is the dynamic behavior of a longer, higher-mass tonearm. A longer arm's moment of inertia is greater. It takes the longer arm more time to react to a warp or eccentricity, and more to "settle" again afterward. Applied in moderation, damping, like a car's shock absorbers, can limit excursions and help control arm behavior.
Longer arms require less of an offset angle, which means there's less skating, but there still is some; some means of applying an antiskating force is still required. SME implements it with a tension spring and filament.

The speed with which audiophiles have adopted a computer of some sort as their primary source of recorded music might be thought breathtaking. But with the ubiquitous Apple iPod painlessly persuading people to get used to the idea of storing their music libraries on computer hard drives, the next logical step was to access those libraries in listening rooms as well as on the move. A few months back, I wrote a basic guide to the various strategies for getting the best sound from a computer: "Music Served: Extracting Music from your PC." Since then, Minnesota manufacturer Bel Canto Design has…
USB-sourced audio data do not necessarily have low jitter, though Bel Canto does claim that the USB Link 24/96 offers low-jitter clock recovery from the USB data (footnote 3). This may be a moot point with the Benchmark and Bel Canto D/A processors, of course, which are modern designs featuring superb rejection of timing errors in the datastreams they're fed. But what about older products? I retrieved from storage a sample of the Assemblage DAC-1 that I'd built from a Parts Connection kit in early 1995, when we published a review by Wes Phillips (Vol.18 No.4). Costing $449 back then, the…

Sidebar 3: Measurements
I examined the measured behavior of the Bel Canto USB Link 24/96 using the Audio Precision SYS2722 system (see www.ap.com and "As We See It" in the January 2008 issue) and the Miller Audio Research Jitter Analyzer. I played back test tones at various sample rates and bit depths from Audacity on a dual-core Pentium PC running Windows XP, and from Audacity and BIAS Peak Pro 6 on a Mac mini running OS10.4.11.
To check whether the USB Link was bit-transparent, I fed its S/PDIF output to an RME soundcard fitted to a second PC and recorded the data using Adobe…
