There's a race on between Sony and Matsushita, to determine who can build the smallest battery-operated CD player with the most features. Sony currently holds the lead with its second-generation D-7 ($300), about 30% smaller than the first "pocket" CD, the D-5. Most of the reduction is in height; both players have a horizontal cross-section only slightly larger than the CD itself. The illusion of smallness is further enhanced by an angled front panel with beveled edges.

The three-day Capital Audiofest runs July 8–10 at the Hilton Hotel at Twinbrook Metro in Rockville, MD. With new, noon–8 pm opening-day hours designed to accommodate 9-5ers eager to top off their Friday with great sound, and completely renovated rooms that should offer even better acoustics than before, the at-capacity show promises 38 exhibit rooms (including 14 large rooms and one two-room suite), and a combined Marketplace/CanMania with 20 exhibitors total. Put that all together, and you end up with 103 exhibitors and brands combined.

Apple is reportedly in exploratory talks to acquire Tidal. Though it's possible that nothing could come of this, and much of the online chatter surrounding this news is processed, regurgitated press release—I'd like to contribute to the speculation by sharing my thoughts: I think it's exactly what the world needs. It would be an intelligent move on Apple's part that would simultaneously benefit listeners, musicians—and of course, boost the high-end audio industry.

Primephonic, a Netherlands-based site that prides itself on its superior classical music metadata, has launched in the United States. Currently devoted to hi-rez classical downloads in WAV (stereo), FLAC (stereo/surround), and DSD (stereo/surround), Primephonic also intends to launch the beta version of its high-quality streaming service later this year.

The SOtM sMS-1000SQ Windows Edition with AudiophileOptimizer and Roon: Not only does that very long name require finger-twisting shifts between upper and lower case, it really doesn't tell you what the sMS-1000SQ WE is.

Korean manufacturer SOtM, Inc. describes it on their website as a "music server based on Windows Server OS besides the original Linux [Vortexbox] OS based sMS-1000SQ." I'd describe it as a Windows-based PC that's designed and optimized to manage a database of music files and stream the music to local or networked DACs, and that supports multiple options for file management, playback, and target devices. (Hmmm: that's not much better, is it?)

Editor's Note: One-bit DAC chips in the 21st century, where the analog output signal is reconstructed from a very high-rate stream of pulses, are ubiquitous. But a quarter-century ago, those chips were only just beginning to stream from the chip foundries. In this feature, we aggregate Stereophile's 1989 coverage of the then-new technology, starting with Peter van Willenswaard on the basics.—John Atkinson.

1989 may well become the year of the D/A converter (DAC). CD-player manufacturers have, almost without exception, launched research projects focusing on this problem area of digital audio; many of these projects are already a year old. This is, however, by no means the only imperfection keeping us away from the high-quality sound we have come to suspect is possible with digital audio media, and maybe not even the most important.

By the time you read this, in the fall of 1967, the "Dolby system" will probably be old hat to you. Every other audio publication has been describing it, discussing it, and hailing it as the greatest invention since sex.

We've seen that kind of press ballyhoo before, about such significant advances as the Edsel, the 16-rpm LP and the "thin-profile" loudspeaker, so our first inclination was to be a wee bit skeptical of the Dolby. It seemed too good to be true.
