Audacious Audio

Is the high-performance audio industry stagnating? Are designers simply repackaging the past? Cynics claim so, but to me it seems that making that case gets harder by the day, as a parade of veterans continue to produce their best work.

"So what kind of music do you listen to?" I heard myself asking Leif Mårten Olofsson, designer of the Coltrane, Coltrane Alto, Duke, Miles II, Mingus III, and Monk loudspeakers, before I could take it back. The small company, headquartered in Göteborg, Sweden, where Volvos are made, has been building and marketing loudspeakers for the past six years, though Olofsson confesses he's been building them for 30 years, ever since he was 12.

Show a time traveler from the 1920s an iPad and most likely he'd neither know what he was looking at nor what it might do. Show him a loudspeaker, even one as advanced as Magico's new Q5 ($59,950/pair), and he'd probably know exactly what it was and what it did, even if what it's made of might seem to have come from another planet.

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 Although Mark Levinson products were originally made by Mark Levinson, they are no longer.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.

Over the past two and a half years, I've auditioned and reviewed a number of digital audio products. It has been a fascinating experience both to watch digital playback technology evolve and to listen to the results of various design philosophies. The road to more musical digital audio has been a slow and steady climb, with occasional jumps forward made possible by new techniques and technologies. Making this odyssey even more interesting (and confounding), digital processors seem to offer varying interpretations of the music rather than striving toward a common ideal of presenting what's on the disc without editorial interjection.

The arrival of the Mark Levinson No.30 digital processor more than 2½ years ago marked a turning point in digital-audio reproduction. Although the No.30's $13,950 price tag put it out of reach of all but a few audiophiles, its stunning performance suggested that much more musical information was encoded on our CDs, waiting to be recovered by better digital processors. Further, it was inevitable that this level of performance would become less expensive over time. I was more excited by the No.30 than I've been over any other audio product. In fact, its musical performance was so spectacular that it alone occupied the Class A category in Stereophile's "Recommended Components."

Mark Levinson founded Mark Levinson Audio Systems in 1972, but sold it, and the right to market audio gear under his own name, to Madrigal Audio Laboratories, then owned by the late Sandy Berlin, in 1984. Harman International bought Madrigal in 1995. As well as Mark Levinson, Harman's Luxury Audio Group now also includes digital processing pioneer Lexicon, speaker manufacturer Revel, and JBL Synthesis. The Mark Levinson brand is now headquartered in Elkhart, Indiana, at the Crown Audio facility, another Harman-owned brand. The No.53 ($25,000 each; $50,000/pair) is Mark Levinson's first new Reference series monoblock since the No.33, way back in 1993, when Madrigal owned the company. Like other Mark Levinson products, it is manufactured at an independent facility in Massachusetts.

Back in the late 1980s, when I was writing for The Abso!ute Sound and couldn't afford any of the audio gear I was reviewing, my system consisted of an Oracle turntable with Magnepan unipivot arm, a pair of Spica TC-50 loudspeakers, and a heavily modified Hafler DH-200 power amp and DH-101 preamp. It was a fun system that imaged like hell, but my fondest audio memories of that time were of visiting fellow TAS reviewer Dr. Michael Gindi, who lived on Manhattan's West End Avenue, and listening to his mbl speakers. (With his shrink's paycheck, he could afford them.)

Don't be confused by the MBL 6010 D's oddly baroque, even retro looks. Behind all the glitz—the oversize, perfectly finished, black-lacquered faáade; the two big, solid brass knobs plated with 24-karat gold; the ornate lettering; and the incongruous digital volume display—resides a thoroughly modern, remote-controlled, unusually versatile, and well-thought-out solid-state preamplifier. Not that the 6010 is a new design. It's been around for a long time, and the current "D" iteration is at least five years old.

A year or so ago, in my review of the Pass Labs XP-30 preamplifier, I wrote that the heart of an audio system is the preamplifier, in that it sets the overall quality of the system's sound. But it is the power amplifier that is responsible for determining the character of the system's sound, because it is the amplifier that must directly interface with the loudspeakers. The relationship between amplifier and loudspeaker is complex, and the nature of that relationship literally sets the tone of the sound quality.

Take a casual look at the Mk.II edition of MBL's Reference 101E Radialstrahler loudspeaker, and you won't immediately see what's new compared with the original version, which I reviewed in October 2004. But the Mk.II has a shorter, sleeker bass cabinet, designed to, among other things, slightly lower the stack of omnidirectional drivers it supports. While the many other major revisions to this familiar and fascinating loudspeaker can't be seen, it's fair to say that, from the ground up, the Reference 101E Mk.II is a new loudspeaker in design, if not in concept.

As large as a small file cabinet and weighing 223 lbs, MBL's most powerful amplifier, the Reference 9011, is a tour de force of electronics design and implementation that will set you back $53,000 if you're a single-ended stereo enthusiast, or $106,000 if you like pure balanced mono.

There are as many ways of designing a digital-to-analog converter as there are engineers. One approach is to select parts from manufacturers' data books and build the product according to the "application notes" provided by the parts manufacturers. This is the electronic equivalent of a paint-by-numbers kit.

A more creative engineer may add a few tricks of his own to the standard brew. Bigger and better regulated power supplies, careful circuit-board layout, tweaky passive components, and attention to detail will likely make this designer's product sound better than the same basic building blocks implemented without this care. Indeed, the vast range of sonic flavors from digital processors containing very nearly the same parts attests to the designer's influence over a digital processor's sound.

It's been a while since I auditioned a Meridian CD player in my system. I had enthusiastically reviewed the English company's groundbreaking Pro-MCD player in early 1986, and over the years had kept up with the progress they were making in digital playback, either through my own reviews or by performing the measurements to accompany reviews by other Stereophile writers. The 508-24 player, reviewed by Wes Phillips in May 1998, was one of the finest digital products of the 1990s, I thought. But when Meridian began promoting surround sound and DVD-Audio at the turn of the century, their goals became somewhat incompatible with my own. Yes, I can appreciate what surround playback can do, but my own musical life is still solidly rooted in Two-Channel Land.

"Is that it?" I asked.
