Electric guitarist John Scofield, winner of multiple Grammy Awards, has a knack for staying a step ahead of musical trends. In hundreds of jazz settings, "Sco" and his signature Ibanez AS200 guitar and Fender Reverb amplifier have created a unique style and sound that have earned him a popularity beyond jazz's usual audience.
"It doesn't feel like I'm ahead of the [curve] at all," Scofield told me, from his home in upstate New York. "Maybe musicians are more attuned to what's happening than the public, just because we're so obsessed with music. But I try not…
I began my Sunday morning at Capital Audiofest with a portion of one of Malcolm Arnold's jaunty overtures: not quite sacred music, but it was nonetheless magnificent in the room sponsored by Gryphon Audio and retailer 20/20 Evolution Systems. In addition to having appropriate weight and realistic die-away, the sound of mallet on bass drum had the most tonally realistic thud I recall hearing through a hi-fi. And on a CD vinyl drop of the mono version of Mal Waldron's "Warm Canto," the unison piano, cello, and double-bass notes in the opening measures had realistically tactile note attacks—…

Editor: This is very interesting. I would urge readers to read the whole of Jon Iverson's review and not just the conclusion.
The accuracy vs listenability debate has run since the beginning of audio time, and will likely outlast both BorderPatrol and Benchmark.
Given the left-brain/right-brain relationship of the BP and Benchmark DACs (as Herb Reichert would have it), alarm bells rang when I saw that John Atkinson had selected the owner of a Benchmark DAC to write the Follow-Up review.
I shouldn't have worried: Jon Iverson was more…

"I've got six hours to get ready for 30 hours of show time so an attendee can listen for 10 minutes." Thus did Doug White, proprietor of the Philadelphia-area dealer The Voice That Is, describe the challenge of setting up a system for a show such as Capital Audiofest. (When I asked, Do you use a spectrum analyzer?, White said Yes, and smiled and pointed to his brow.) The results of his expertise—no other word for it—were in full flower in a system that, though far from humble, featured the least expensive loudspeakers I've heard in a TVTI system: Tidal's Vimberg-series Mino ($29,000/pair).…
Japanese audiophiles venerate American high-end audio components, paying huge sums for vintage Marantz tube amplifiers, racks of Levinson ML-2s, and early Audio Research tube preamplifiers. The balance of trade, at the high end anyway, hasn't been reciprocated: Japanese high-end amplifiers and preamplifiers have not received as positive a reception in the US. Perhaps it was a matter of styling, but the sonics of the Sony Esprit line and the class-A Stax amplifiers did not receive the following they might have, had the products been American.
In the past five years, a number of Japanese…
By far the most complicated of the three preamps i review in this issue in terms of facilities offered, NAD's "Monitor Series" 1300 ($398) provides two buffered tape loops, an external processor loop (which can also be used as a third tape-recorder loop), a headphone output, a "null" switch, switchable bass equalization to extend the low-frequency range of small loudspeakers, and treble and bass controls, each with a choice of three turnover frequencies: 3kHz, 6kHz, 12kHz, and 50Hz, 125Hz, 250Hz, respectively. An 18dB/octave infrasonic filter, cutting the response below 20Hz (–3dB at 14Hz)…
