Recording of October 1987: Duruflé & Fauré <I>Requiems</I>

Duruflé: Requiem; Fauré: Requiem
Blegen, Morris, Shaw, Atlanta SO and Chorus.
Telarc 80135 (CD). Robert Woods, prod.; Jack Renner, eng. DDD. TT: 74:23

To have two Requiems by French composers on the same disc certainly invites comparisons. Superficially similar, the works are actually quite different: both are conceived for small-scale performance, both rely on the organ, and neither places any great demands on chorus or orchestra. The differences concern mood and even intent. Fauré's Requiem, composed between 1887 and 1890, has survived all kinds of performances, both amateur…

Spendor BC-1 loudspeaker

This smallish loudspeaker system has been getting high ratings in the English audio magazines for some years but was not available to US consumers until recently, when the small firm (literally a Mom'n'Pop enterprise, footnote 1) arranged for US distribution through Audio International.

The Spendor BC-1 is about as unimpressive-looking as any other smallish three-way loudspeaker, of which there are countless hundreds of models being made in the US at present. In fact, we were so ho-hummed by the mundane appearance of this speaker that we found it hard to connect the pair up and give them…

Bel Canto Design Aida D/A processor

John Stronczer, Bel Canto Design's technical spark plug, meets my definition of an electronics renaissance man, ranging as he does from designing single-ended amps that glow in the dark (the Orfeo) to digital processors (the Aida). Actually, digital circuitry is one of John's specialties, dating back to his days at Honeywell.

The Aida is a prime member of Bel Canto's "operatic" series, which includes the Tosca and the Fidelio. John told me that the Aida was developed to provide a digital audio source that could compare with and be enjoyed alongside a high-quality analog system. In…

Bel Canto Design Aida D/A processor Review System

Sidebar 2: Review System

Preamplifiers included the Jadis JP-80MC, the Air Tight ATC-2, and the Sonic Frontiers SFL-2 Signature. CD transports were the Micromega Trio CD2, California Audio Labs' Delta, and the Accuphase DP-90. After experimenting with several 75 ohm digital interconnects, I settled on Mapleshade Electronics' Omega Mikro-D and Acrotec's D5010 datalinks as offering the most synergistic sonic match. Reference D/A processors included the Sonic Frontiers SFD-2, Theta's DS Pro Gen.III, CAL's Alpha processor, the original PS Audio UltraLink, and the Accuphase DC-91.

Bel Canto Design Aida D/A processor Measurements

Sidebar 3: Measurements

The Bel Canto Aida had one of the lowest output levels I've measured from any processor: just 1.4V when decoding a full-scale, 1kHz sinewave. Unusually, the output level was identical from the unbalanced and balanced outputs. Although the Aida had a low output impedance of 90 ohms, the 1.4V maximum output level may not be enough to drive some power-amplifier/loudspeaker combinations to adequate listening levels without an active preamplifier. The Aida doesn't invert absolute polarity; a positive-going impulse on a CD produces a positive-going output signal. The…

Sony DTC-2000ES DAT recorder

Introduced nearly eight years ago as the first recordable digital format for consumers, DAT both failed to appeal to its target market and was blocked from formally entering the USA for four years by the RIAA, who feared for the copyright of its members' recordings. However, the DAT medium was enthusiastically snapped up by professionals and semiprofessionals, who found its combination of reliability, CD-compatible signal format, and editing ease ideal for mastering. Sony currently offers a small range of consumer models, from the diminutive Walkman-sized TCD-D-7 DATMan to four-head cassette-…

Sony DTC-2000ES DAT recorder J. Gordon Holt Again 1995

J. Gordon Holt wrote again about the Sony DTC-2000ES in December 1995 (Vol.18 No.12):

When the review sample of this Super-Bit-Mapped DAT deck returned from RH's testing facility, the drawer-close spring was broken. (The unit had been used, perhaps, 30 hours during my tests, 3 during his.) I was able to jury-rig a repair of this, but shortly thereafter one of the pivots popped out of the tape-loading bar and disappeared into the innards of machine, making it impossible thereafter to load a tape.

Fortunately, the unit I'd purchased (yes, I decided to take the plunge, despite the…

Sony DTC-2000ES DAT recorder Dis'n'DAT

Sidebar 1: Dis'n'DAT

DAT is a format unlike any other. The tape cassettes use 1/8"-wide tape running at 0.3"/second, and run on what is basically an ultra-miniature VCR that records in a series of diagonal stripes across the tape (helical scan). The recordings have extraordinarily robust error correction (footnote 1), and can use several kinds of place markers that together constitute a rudimentary, but effective, editing system.

A start identifier (ID) signals the beginning of a recorded selection, and can provide a seek point for high-speed searches to specific locations on the…
