LATEST ADDITIONS

For a decade, the sound of the Vivid Giya loudspeakers, which I had heard only at CES in private demonstration suites, beguiled me. My positive impressions were completely consistent from one show to the next—but then, so were the host and the surroundings. I had to wonder how much those factors contributed to my impressions.

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.

It's 3am. You're lying in bed. Something woke you up—you don't know what it was. You pull back the covers, get up, and tiptoe out to your listening room.

There, standing by your record rack, thumbing through your prized LPs, is a man in black (no, not Johnny Cash—a different man in black). You see a bulge in his pocket; it could be a gun. Something shiny catches your eye—there's a switchblade knife between his teeth! At his feet, leaning against your record shelf, is a cudgel. Oh, and it looks like he might have some infectious disease. You, of course, are in your PJs.

You notice, at the top of the stack of records that he holds under his arm, that one record, the one you love the most, the one you can't live without.

On Friday, January 17 from 5-9pm, Innovative Audio in New York City will debut the Wilson Chronosonic XVX, Wilson's flagship loudspeaker.
