Solid State Power Amp Reviews

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.

When I first saw Anthem Statement's M1 at the 2011 CEDIA Expo, it was a bolt from the blue. Happening on this flat, black slab of an amplifier lying on a display table or bolted to a wall, reminded me of the appearance of the iconic monolith in Stanley Kubrick and Arthur C. Clarke's 2001: A Space Odyssey. The M1's dimensional ratios are not 1²:2²:3², and there are many other one-rack-unit amps—yet, like the monolith on the moon, the M1 was in such striking contrast to everything else in its environment that it demanded attention and reflection.

A recent (unpublished) letter to the editor argued that the reference for audio perfection is the sound of real instruments in a real space. The writer claimed that, since the art and/or science of audio is advancing, and because it is a "scientific truth" that the closer you get to perfection, the less divergence there is components, that therefore there should be less difference in sound among the components listed in Class A of Stereophile's "Recommended Components" than among those in Class B, much less Class C. This should be true of loudspeakers, he said, but even more true of top-rated amplifiers, since "they inherently have less divergence."

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 $120,000 if you like pure balanced mono.

"That's just silly on so many counts, Antony."

I was talking last winter to Musical Fidelity's Antony Michaelson, who had been enthusing about his forthcoming stereo amplifier, the AMS100. It would be physically enormous—almost a yard deep—and commensurately heavy at 220 lbs. Despite its bulk, its maximum rated output would be just 100Wpc into 8 ohms. It would also be expensive, at $19,999. And to cock a snoot at environmentalists and their concerns, the AMS100's output stage would be biased into class-A up to its rated 8 ohm power, meaning that, even when not playing music, it will draw around 10 amps from a typical US wall supply of 120V. This also means that it will run very hot, making the amplifier impracticable for summer use in homes without central air-conditioning. Like mine.

That is not a typo. The company is named Soulution—as in soul commitment to designing and manufacturing the finest audio gear it knows how, as in souldiering on in the face of skeptics who can't imagine why a power amplifier that puts out 130Wpc into 8 ohms or 260 into 4 ohms should cost $45,000, or weigh as much as a small pickup truck.

Audio reviewers are kinda slutty. Not sexually, of course, but in the way we promiscuously go through equipment. Like the most popular girl in school, or Tiger Woods, we have our choice of any hot thing we want, whenever we want it. Heck, reviewers don't even have to pick up equipment at bars or clubs: the stuff is delivered right to our homes. We use the gear for a few months, then send it packing once the next hottie comes over to play in our room.
