Crystal Clear CCS-7003 (Direct-cut LP). Ed Wodenjak, prod.; Bert Whyte, eng.; George Piros, Richard Simpson, Stan Ricker, mastering; John Meyer, special equipment; John Curl, console design.
One of Crystal Clear's earlier releases (1978), this has very distant, directionally vague sound, but the sound (stupendous by standards of only a few years ago) cannot stand in the way of two of the most exciting performances of these potboilers that have ever been committed to…
The KSL ($1800, $2100 with phono section) is a one-box line controller/preamplifier, just 2.25" high, with a nominal voltage gain of 10dB, or 3x. Despite its moderate price, the KSL is distinguished by having balanced outputs (via industry-standard XLR connectors), as well as two balanced inputs. Conventional single-ended, unbalanced outputs are also available via a pair of gold-plated phono sockets. Two unbalanced inputs are provided, plus a third via the tape monitor switch. The tape output is unbalanced, derived from the selector switch setting, while the main outputs may be used…
Sidebar 1: A Matter of Balance
Much has been written about balanced operation, but few real facts have been established except for its frequent use in professional studio applications, where it was primarily developed for low-level microphone signals and long cable runs, sometimes as long as 100m. By using an intimately twisted pair of conductors (which offers good rejection of external electromagnetic interferences when driven in a push-pull balanced mode), then shielding the assembly, often with two successive dense-wire braids, external hum and noise fields could be suppressed. The…
Sidebar 2: Ancillary Components
A well-judged assessment of equipment of this quality requires several conditions to be satisfied. First, the equipment must be conditioned, run-in for several days, and well warmed up. Second, its mode of use and the chosen interfaces should be carefully selected, with allowance made for some experimentation to determine the optimum arrangement. This area includes balanced and unbalanced operation, and the choice of cables. Third, it's valuable to have a handful of comparable and reference components with which to compare. In the case of the KSL…
Sidebar 3: Measurements
As might well be expected, harmonic distortion levels were negligible—better than –83dB over the measured 20Hz–20kHz range at a nominal 0.5V IHF output level. With class-A circuitry, fully complementary harmonic orders were low, with quite negligible upper-range harmonics. The two-tone high-frequency intermodulation test generated a very low –89dB level of in-band difference tone. Little variation was observed at higher or lower signal levels. Virtually a little power amplifier in its own right, the KSL could deliver a maximum voltage swing of 8.7V RMS from a very…

1915. Marcel Duchamp's nude has already descended the staircase, Arnold Schoenberg's Three Orchestral Pieces, Op.16 have shattered tonality, and the old order is crumbling. World War I is well upon us, bringing with it human-caused suffering and destruction on a scale never before experienced in human history.
It is in 1915 that 30-year old Alban Berg finally heeds the advice of Schoenberg, his longtime mentor, unleashes his talents on full orchestra, and completes his Three Pieces for Orchestra, Op.6. Although the 22-minute composition pays homage to Gustav Mahler (1860–1911) in its use…
Featuring Mytek's MQA-equipped Manhattan II D/A preamplifier-headphone amplifier on its cover, our new issue—132 pages of awesome—is jam-packed with good stuff. There are reviews of Ayre's QX-5 Twenty "digital hub," Kii's ground-breaking, DSP-optimized active speaker, amplifiers from Bel Canto and Octave, and preamplifiers from Shindo and Sutherland. Jim Austin interviews Pass Labs' onlie begetter, veteran engineer Nelson Pass. Robert Baird surveys audiophile-quality reissues of horror-film soundtracks. Mikey Fremer visits revitalized SME in the UK. And kicking it all off, Art Dudley condemns…
Art Dudley and Herb Reichert are back! In this third (and final) video conversation that I shot in Art's living room, Art and Herb have a friendly debate about stereo imaging and talk about what matters to them when it comes to the reproduction of music.

"[We] know the truth of this: We would likely live happily ever after with a system from nearly 60 years ago. An idler-drive turntable, some Marantz electronics, and Quad ESL-57s can be very satisfying. The main improvements to be made are not necessarily in the area of musical enjoyment, but rather boring old reliability."
Charley Hansen of Ayre Acoustics, who made these observations in an e-conversation two years ago, gives…
