Integrated Amp Reviews

Having evaluated any number of integrated amplifiers in the past year or so, I've repeatedly been impressed by the ways in which designers build versatility and sonic distinction into their single-box designs. In matching those that sounded and measured the best—such as the tubed E.A.R. V20 (October 1999) and the solid-state Magnum Dynalab MD 208 receiver (January 2001)—with appropriate speakers and source components, I was able to attain high-resolution musicality with a minimum of fuss. Crave high-end sound but require even less complexity? You could dispense with interconnects altogether by integrating a high-quality CD player into a remote-controlled receiver, as Linn has with the diminutive Classik that I reviewed last November.

In the ongoing audiophile debate over the relative merits of solid-state vs tube amplification, compelling cases can be made for the overall musicality of both methods. And while there's a lot to be said for the dynamic headroom, bass focus, clarity, frequency extension, and silent performance of solid-state gear, it's funny how much you can come to miss the aural verities of tube electronics after a prolonged absence.

Why would a sharp mind offer a $15,000 integrated digital amplifier to a reviewer who has been characterized in the audio press as the "self-proclaimed Analog Messiah" and a "hyper-Luddite"? That's the first question a self-centered reviewer asks himself. Yours might be: "A $15,000 integrated amplifier from...Sharp?"

"Heard anything great?"

As strongly as I believe that the listening experience is the most reliable method of judging the quality of audio equipment, I've been biased against single-ended tube amplifiers because of their quirky measured performances. Without having heard single-ended under good conditions—much less living with an SE amplifier—I had concluded that many listeners must like them because they're euphonically colored by large amounts of low-order distortion and impedance interactions with the loudspeakers. SE amplifiers seem to be a departure from the goal of making the electronics transparent. Moreover, the range of loudspeakers suitable for SE amplifiers is so restrictive that I wondered why anyone would bother with these underpowered distortion-generators. I had fallen into a trap that I've repeatedly railed against: drawing conclusions without firsthand listening experience (footnote 1).
