At the 1992 Winter Consumer Electronics Show in Las Vegas, Audio Research showed a line of reference products that represented the pinnacle of founder William Z. Johnson's life work as an amplifier designer. Although the all-tubed, fully balanced preamplifier and tubed monoblock power amplifiers were shown as works-in-progress, it was clear that these were products aimed at advancing the state of the amplifier art with no consideration for cost.

From the front, the LS5 looks identical to Audio Research's popular LS2: two knobs on either side of the Audio Research nameplate, and a row of toggle switches along the bottom. But that's where the similarities end; the LS5 is a completely different animal from the LS2, or even the balanced LS2B.

Tell me now: When you're there in the scene, watching Lord Voldemort chase Han Solo through the Cave of the Klan Bear, how often do you notice that the sounds you're experiencing are being pumped at you from five black-painted room boundaries, while the flickering-light images approach from only one? Moreover, in a parallel, more quotidian reality, you're sitting upright in your seat, noisily chomping popcorn while absorbing—and processing—massive amounts of sensory data: Did you ever consider the sensual, mechanical, and psychological complexity of a moment like this, and how fundamentally unnatural it is?

Of the celebrated triumvirate of John Scofield, Pat Metheny, and Bill Frisell—the most original and influential jazz guitarists of the past 50 years—none is more distinctive, or self-effacing, than Frisell, a true changeling of the guitar. Frisell is a jazz-based musician, but his music crisscrosses genres, and his guitar playing isn't bound to or limited by a specific technique. He's a master illusionist, able to alter a song's meaning far beyond its original intent with the aid of a Telecaster guitar, a modest effects chain, and, most importantly, his rich imagination.
