Computer Audio Reviews

As readers of the Stereophile eNewsletter will be aware, the twin subjects of distributing music around my home and integrating my iTunes library of recordings into my high-end system have occupied much of my attention the past year. I bought an inexpensive Mac mini to use as a music server, using an Airport Express as a WiFi hub, which worked quite well, but my big step forward was getting a Squeezebox. I described this slim device in the mid-March and mid-April eNewsletters; I urge readers to read those reports to get the full background on this impressive device. In addition, the forums and Wiki pages on the Slim Devices website offer a wealth of information on getting the most from a Squeezebox.

Usually, a Stereophile "Follow-Up" follows up (duh!) a full review of the component in question. This review, however, is intended to flesh out a cryptic comment made by Wes Phillips in April's "As We See It": "When Apple introduced its AirPort Express wireless multimedia link," Wes wrote, "it even included a digital port so that an audiophile—such as Stereophile's editor—could network his system, using the AE to feed his Mark Levinson No.30.6 outboard D/A converter. 'Sounds okay,' deadpans JA."

Computers and vacuum tubes go together like Trent Lott and flyaway hair, right? The last time filaments glowed in computers was during the 1960s, when a computer was a building. I remember laughing at the ponytailed computer-science dweebs back then, who spent their college days playing nursemaid to a football field's worth of electronics capable of little more than adding two plus two. Chained to a computer half the day, as most of us now are, guess who had the last laugh?

In the early days of digital audio, I remember talking with Dr. Tom Stockham, the developer of the groundbreaking Soundstream system used then by Telarc. As well as using a 50kHz sample rate, the excellent-sounding Soundstream stored its 16-bit data on large drum-shaped Winchester drives connected to a minicomputer. Twenty years later, the advent of ultra-high-density magnetic storage media and fast microprocessor chips has put high-resolution digital audio manipulation and storage within reach of anyone with a modern PC or Mac. And facilitating the transformation of the PC into a high-quality DAW has been a new generation of soundcards, such as the Digital Audio Labs CardDeluxe I reviewed in September 2000 and the subject of this review, the German RME Digi96/8 Pro.
