I initially used the e1X DAC for several days of casual listening, to make sure all was working correctly. I then started the critical listening, primarily using recordings that I had made myself. Low frequencies were well-defined with good weight, high frequencies were neither exaggerated nor rolled off, and the midrange sounded natural. It was difficult to ascribe an identifiable tonal character to the Bel Canto. As I kept listening, the thing that struck me was how clear a view into recorded soundstages I was experiencing. Whether it was the subtle acoustic of Robert Silverman's 1992…

Sidebar 3: Measurements
I measured the Bel Canto e1X DAC with my Audio Precision SYS2722 system. Looking first at the digital inputs, the AES3 and coaxial S/PDIF inputs accepted data sampled at all rates up to 192kHz; TosLink was restricted to 96kHz data. Apple's AudioMIDI utility revealed that the e1X accepted 24-bit integer data via USB sampled at all rates from 44.1kHz to 192kHz. (The print manual says 384kHz.) Apple's USB Prober app identified the Bel Canto as "Bel Canto Hi-Res 2" from "Bel Canto" and the USB port operated in the optimal isochronous asynchronous mode.

The earliest direct-drive record player I've discovered is Garrard's Model 201 from 1930. It only played 78s. In their advertising, Garrard claimed the 201 was the world's first "transcription turntable." It employed Garrard's latest in a line of what they called "prestige" motors: an AC-induction "Super Motor." Garrard described the 201's platter as "plush covered" and said it was "popular with HiFi enthusiasts and used by the BBC." The 201 was superseded by the 201A, which rotated at both 78 and 33 1/3 rpm. The venerable Garrard 301 that followed was an idler-drive design.

The Stealth comes stock with Ortofon's 2M Blue moving magnet phono cartridge, which, according to my Feickert protractor, was set to a Stevenson alignment. The Blue features a Hopelex body and a well-designed, safe-to-use stylus protector. Its magnets are attached to an aluminum cantilever tipped with a nude elliptical diamond. It weighs 7.2gm and produces 5.5mV output. The recommended vertical tracking force is 1.6–2.0gm.
From left to right on the Stealth's rear are twin RCA connectors that are directly connected to the tonearm's wires, a ground terminal, a slider switch for turning…

Founded in 1926 by Guy R. Fountain in London as the Tulsemere Manufacturing Company, Tannoy—a portmanteau (footnote 1) of "tantalum" and "alloy," after a tantalum-lead alloy used in rectifiers—took on its current commercial identity in 1928. Through the war years and beyond, the company specialized in public-address (PA) systems. Indeed, today, "tannoy" is a widely recognized generic term for a PA system in the UK; there's an entry for "tannoy" in the Oxford English Dictionary.
Tannoy was 20 years old when the company introduced, in 1947, its Dual Concentric drive unit, the basis of…
The Dual Concentric's tweeter uses an aluminum-magnesium– alloy dome driver with, as previously mentioned, Tannoy's Point Source Tulip Waveguide. The woofer part utilizes a 10", treated-paper-pulp cone with an HE twin-roll fabric surround and a 1 5/8" (42mm) edge-wound voice-coil. "The HE refers to the hard-edge, impregnated fabric surround on the bass driver, which stores less energy and gives it a faster and more articulate sound than its predecessors," Deal added.
"The high-frequency driver is a wide-dynamic-range compression unit," Deal wrote. "The Tulip Waveguide is a low-…
