Historical

Even as digital/analog processors were becoming a hot product category in the early 1990s, audiophiles were also learning that timing uncertainties in the AES/EBU and S/PDIF serial datastreams—jitter—would compromise any improvement in sound quality offered by these DACs. Some companies therefore introduced products to reduce or eliminate jitter—in the November 1994 issue of Stereophile, Robert Harley reviewed three such products: the Audio Alchemy DTI Pro, the Digital Domain VSP, and the Sonic Frontiers UltrajitterBug. I still have Stereophile's review samples of the UltraJitterBug and VSP, along with two contemporary DACs: a PS Audio UltraLink and a Parts Connection Assemblage DAC-1.

As our reviews of these products were published before Paul Miller's and the late Julian Dunn's development of the "J-Test" diagnostic signal, I performed J-Test jitter measurements to bring that 1994 review into the 21st Century. You can see what I found here.

This month I am writing about five vintage loudspeakers you should hear before you die.

Why vintage? Because the best vintage gear offers an abundance of musically agreeable qualities that are missing from even the best contemporary gear.

Nineteen days after J. Gordon Holt died, my daughter and I drove west on NY Route 20, passing lawn sale after lawn sale on our way to the supermarket in Richfield Springs. Each sale promised a pleasant waste of time on that hot afternoon, but only one caught my eye: There, among the Avon bottles and the 8-track tape cartridges, were two large bookshelf loudspeakers, dressed in walnut veneer and light-colored fabric grilles. AR 3s, I thought. Or maybe Large Advents. "They'll still be there when we come back this way," I said, stupidly.

Editor's Note: John Crabbe was Editor of Hi-Fi News & Record Review when I joined that magazine as a lowly editorial assistant in September 1976. At the end of 2007, I had asked Steve Harris to interview John for Stereophile, as part of an ongoing project to create an oral history of high-end audio (footnote 1). Sadly, John passed away in December 2008—see "As We See It" and "Industry Update," in our March issue. We are publishing Steve's interview as a tribute to a man from whom I learned my craft as an audio magazine editor.—John Atkinson

One day last year, my friend Larry and I were talking about our college-fraternity days and loudspeakers. Those were four of the best years of my life. Strong friendships were formed, and ever since, we've kept in touch with most of our fraternity's brothers-in-heart. Ours was not a jock house, nor was it the last bastion of rampant male sexuality—it was, after all, an MIT frat house. But it was full of music lovers who fell neatly into three camps: the California School owned JBL Decades, the New England School had Smaller Advents, and the Renegades boasted bootlegged Bose 901s (footnote 1).

Back in 1964, Avery Fisher, founder and president of the Fisher Radio Corporation, wrote a short note for the 500-C Stereophonic FM Multiplex Receiver owner's manual. In that note he said, "a door has opened for you, and your family, on virtually unlimited years of musical enjoyment."
