Founded in 1925, Luxman has long been one of Japan's most highly regarded audio manufacturers. Throughout the 1970s and into the 1980s, Luxman's tube preamplifiers and power amplifiers occupied the top shelves of high-performance audio retailers, and to many older American audiophiles, the Luxman name is as familiar and esteemed as those of such storied American brands as McIntosh and Marantz. Luxman's combination of rich, warm sound, superb build quality, and indelible industrial design made its products fully competitive with other brands then considered among the world's best.

Some of the old audio names, such as Eico and Pilot, are gone. Others—Fisher, AR, KLH, H.H. Scott, etc.—have been rendered meaningless by corporate mergers and acquisitions. Yet more than 50 years after their founding, McIntosh and Marantz, arguably the two most prestigious names in American high-quality audio electronics, survive. The products they make today are probably closer in spirit to their original classics of half a century ago than at any time since the early 1970s.

"A high-quality amplifier must be capable of passing rigid laboratory measurements, meet all listening requirements, and be simple and straightforward in design in the interest of minimizing performance degradation..."—Cdr. Charles W. Harrison Jr., Audio, January 1956 (footnote 1)

I must admit, right from the outset, that I find reviewing electronic components harder than reviewing loudspeakers; the faults are less immediately obvious. No preamplifier, for example, suffers from the frequency-response problems endemic to even good loudspeakers. And power amplifiers? If you were to believe the older generation of engineers—which includes some quite young people!—then we reached a plateau of perfection in amplifier design some time after the Scopes Monkey Trial but well before embarking on the rich and exciting lifestyles afforded us by Reaganomics. (In the UK, it is generally felt by these people that the date coincided with the introduction of Quad's first current-dumping amplifier, the 405, in 1976.)

I still remember reading about my first Mark Levinson product 14 or 15 years ago. It was a preamp. The model number escapes me, but it sold for over $2000. It was soon followed by the JC-2, designed by John Curl, which was a bit less pricey but still astonishingly expensive for a mid-'70s preamp. We've come a long way since then. The man, Mark Levinson, left the company that bore his name in the early 1980s and founded a new company, Cello. The company Mark Levinson became the core of Madrigal. It is a mark of their continued dedication to uncompromising high-end products that their bread-and-butter line remains the high-priced Mark Levinsons. They no longer have the Rolls-Royce of the audio market to themselves (in their early years, they made the never exactly inexpensive Audio Research products—ARC was certainly a contender for the same title—look like bargains), but they are certainly a leading player.

The No.331 is the latest iteration in a series of Mark Levinson 100Wpc, solid-state, stereo power amplifiers. Extensive cosmetic alterations, internal structural changes, and new circuit designs make it quite different from the No.27 and No.27.5 models that preceded it. These design refinements emanate from Madrigal Audio Laboratories' latest flagship amplifier, the $32,000/pair, 300W RMS Mark Levinson No.33 Reference.

If I've read it once in mainstream audio magazines, I've read it a hundred times: "The most important component in a system is the loudspeaker, because it is the loudspeaker that makes the sound." Putting aside the obvious illogic of this statement—that without other components in the playback chain, even the perfect loudspeaker can't make a sound—my experience is that it just is not so. Yes, it is true that changing from one loudspeaker to another makes the greatest overt changes in a system's sound.

My father could not resist buying electronic and photographic gear. As soon as he heard about a new Polaroid camera, or a new weather radio, tape recorder, or color television, he'd go shopping. He'd be even more eager to buy an updated version of what he already had, particularly if this meant there was a story to tell. He'd buy one for himself, and sometimes he'd give me and my three brothers one of our own for a birthday or Christmas gift. (I often thought he took more pleasure from giving to us than he did from getting his own.)

Chances are you've never seen an amplifier quite like the Mark Levinson No.33H. That's because there's only one other amp that's anything like it: the Mark Levinson No.33, upon which it's based. Both amps are more tall than broad, looking almost as though they're resting on their ends; heatsinks cluster around their side-panels. In the city of the High End, the No.33 and No.33H are skyscrapers standing tall above the warehouses.

Although Mark Levinson Audio Systems components continue to be produced, the company's headquarters moved in late 2003 from the Madrigal plant in Middletown, Connecticut, to Harman Specialty's facility in Bedford, Massachusetts. There ML shares manufacturing and sales space with Harman's other high-end lines, Revel and Lexicon.

All high-end audio companies turn over their product lines periodically. Even those amplifiers I have depended on as references go out of production. Although my reference amplifier can remain a part of the reviewing sequence, readers won't be able to purchase a discontinued model and get the results I describe. Thus I am compelled to get a review sample of a new amplifier or speaker, and hope for the best.

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.

"Larry, you have too many amplifiers!" exclaimed John Atkinson during a recent visit. This surprised me—I didn't think it was possible to have too many amps. While I'm not going to open an amp museum, I do have a starter collection of Mark Levinson amplifiers from different eras. This either makes me exactly the right or the wrong person to size up Mark Levinson's new No.532H.

When I reviewed the Mark Levinson No.536 monoblock, I said that its sound quality was second to none. However, its stratospheric price of $30,000/pair unnerved me—only seven of the 35 top-rated solid-state power amplifiers listed in the April 2017 edition of Stereophile's "Recommended Components" cost more, and a similar number (not the same models) deliver more power into 8 ohms. "But don't despair," I wrote—"Mark Levinson has just released a less expensive version of the No.536: the dual-mono, 350Wpc No.534 stereo amp ($20,000)." I requested a review sample of the No.534, to see if it matched the No.536's outstanding qualities of build and sound.

Dinesh Paliwal, CEO of Harman International Industries, was addressing engineers and the audio press in a crowded conference room at the opening of Harman Luxury Audio's new Engineering Center of Excellence (ECOE), in Shelton, Connecticut. Paliwal singled out as the ECOE's first beneficiary the Mark Levinson brand, with the goal of revitalizing it as Harman's flagship marque. (Other brands in the HII stable include Harman Kardon, Infinity, JBL, Crown, AKG, Lexicon, and Revel.) To achieve this, he gave the ECOE team access to Harman's R&D budget of $400 million; brought on Todd Eichenbaum, formerly of Krell, to be its Director; and hired 11 more engineers.
