Solid State Preamp Reviews

Klyne Audio Arts has an almost Zen-like approach to the design of its products. Like the best Japanese designs, Klyne's preamps are aesthetically pleasing in appearance, do exactly what they're supposed to, and their controls are not only where you would expect them to be, but have an almost sensually smooth action. Internal construction, too, is a work of art—the kind of design which, transferred to a tapestry, would grace the wall of any listening room. You have to see the insides of a Klyne preamp to appreciate how attractive-looking an audio component can be. But physical beauty is only one aspect of Stan Klyne's designs; of all the electronics manufacturers I know of, Klyne Audio Arts also makes products more adjustable than any others, so as to appeal to the needs of what I call compulsive tweaks.

One of the most striking aspects of high-end audio is that you can never take any component for granted. Most of the radical change in audio at present takes place in new front-end and speaker technologies, but other components are changing as well—and with at least as much impact in making recorded music seem believable.

Before launching into Stereophile's first-ever report on a Mark Levinson product, an important point needs to be clarified. Although Mark Levinson products were originally made by Mark Levinson, they are no longer. Au contraire, Mark Levinson products are now being made by Madrigal, Ltd., which bought Mark Levinson Audio Systems' assets and trademark two years ago. Mark Levinson's products, as distinguished from Mark Levinson products, are now being manufactured by a company called Cello. But the subject of this report, the Mark Levinson ML-7A preamplifier, is a product of Madrigal, Ltd., not of Cello. Now that I've made that all perfectly clear, we may proceed.

Prologue: The context for this review is that back in the 1980s, preamplifiers and integrated amplifiers with remote controls didn't exist. In early 1985 I borrowed a sample of Acoustic Research's Stereo Remote Control, which I believe was designed by Ken Kantor (later to find fame with NHT) and set it up in my bedroom. It drove a pair of powered loudspeakers with auto turn-on, and I very quickly grew to appreciate, not just the sound quality, but the convenience of being able to control the system from the comfort of my bed. So what did JGH think of the SRC?—John Atkinson

The Model 34 preamplifier is the component from English manufacturer Quad that will disenchant perfectionists, partly because of its obvious pandering to connoisseurs of old and sometimes lousy-sounding records, and partly because of its sound.

This solid-state design is supplied with a built-in moving-magnet cartridge preamplifier, and a moving-coil preamp is included with it for (easy) installation by the user if desired. (Remove two screws, pull out the old module, plug in the new one and replace the screws. The job takes about 3 minutes.) The MC preamp supplied is for 20 microvolt-output cartridges—contrary to the instruction booklet's statement that the supplied one is the 100µV version. Modules having a rated input level of 100 or 400µV are available as extra-cost options.

Our first sample of this preamplifier was returned to the manufacturer before we had completed our tests on it, and was replaced with the latest version (ours is serial number 500108). Enough time elapsed between the time we shipped back the first sample and the time we got around to auditioning the second that we are unable to report on any sonic differences between the two.
