For many, the current hot topic in the world of high-end audio is Direct-Stream Digital (DSD), a method, developed by Sony and Philips, of digitally encoding an analog signal. The irony is that DSD is nothing new. The basis of the technology dates to 1946. Stereophile described it in “Industry Update,” as early as Vol.19 Nos.1 and 5, and again in Vol.20 No.9. And, almost exactly 14 years ago, in November 1999, John Atkinson went into greater detail, contrasting DSD with the more common Pulse-Code-Modulated (PCM) encoding used on CD:

In July 2004, I reviewed Jim Cogan and William Clark's Temples of Sound: Inside the Great Recording Studios, a collection of the business histories of 15 US recording studios. Each chapter covered a particular studio, focusing on its role in the careers of the recording artists most associated with that studio; eg, United Western Recorders and the Beach Boys.

Stravinsky: The Firebird (1910 Suite)
Debussy: Prelude to the Afternoon of a Faun
Los Angeles Philharmonic, conducted by Erich Leinsdorf
Sheffield Lab Direct-to-Disc Lab 24 (LP). Lincoln Mayorga, prod.; Doug Sax, James Boyk, engs.

For some reason, Stereophile didn't receive an early pressing of Sheffield's latest orchestral recording, their first since the Wagner and Prokofiev discs back in 1977. So, guess where my review copy of this finally came from? From Harry Pearson, that's who. How did this come about? Well, I had seen a passing comment in The Absolute Sound to the effect that HP didn't like the recording, and since I was favorably impressed with what I'd heard of it at the last two Consumer Electronics Shows, I phoned HP to ask what he didn't like about it. "Dull high end, closed-in sound, not enough spaciousness" was the reply. Thank you, I said. Several days later, a copy of the disc arrived, postmarked Sea Cliff, NY.

Thank you Harry, but I must disagree with you about this recording.

Friday, November 22–Sunday, November 24: The Hi-Fi Expo Sofia will be held at the Grand Hotel (1 Gurko Street, Sofia, Bulgaria). Over 250 high-end brands are expected to exhibit. Show manager Gergana Boeva reports that attendance has grown steadily over the show's first three years, attracting visitors from all throughout Bulgaria, as well as neighboring countries Serbia, Macedonia, Greece, and Romania. For more info, including a complete list of exhibitors, visit the show’s official website.

Tel Aviv’s Vaadat Charigim debut album The World is Well Lost is understated. Simple guitar strums emerge from a low-lying cloud of noise. Drums are pushed to the background while singer/guitarist Juval Haring’s steady stream of baritone strides then tumbles. His syllables topple across the band’s constant pulse. Haring sounds tired, but the never-ending push of The World is Well Lost won’t let him give up.

These are some of the most lusciously transparent-sounding headphones we've ever put on our ears, but we doubt that they will every enjoy much commercial success, for a couple of reasons.

The match between amplifier and speaker for single-ended operation is critical, which is why John Atkinson suggested I let Wavelength's Gordon Rankin lead when it came to choosing a speaker to partner his special-edition Cardinal amplifiers. If you're not talking roughly 92dB sensitivity and a fairly benign load, say no lower than 6 ohms, you're just not talking single-ended. That precluded running the Cardinals on the big Avalon Ascents with their lowish 86dB sensitivity (in spite of the relatively benign impedance curve).

After more discussion it became evident that the best speakers to use were the very ones Gordon employed in his own reference system—the Swiss-made Reference 3A Royal Master Control loudspeakers.
