Audacious Audio

The old Saab slogan, "Find Your Own Road," was so good that the old General Motors, which once owned Saab, had to kill it—just as the newly revived GM tried, in a "Call It Chevrolet" memo, to kill "Chevy." GM did a U-turn on that one the very next day, but "Find Your Own Road" never returned, and is available for Ayre Acoustics to use. I can't think of a better slogan for a company that I admire almost as much as I do Saab.

Consider this: While Ayre calls its new DX-5 ($10,000) a "universal A/V engine," the disc player doesn't have a coaxial or a TosLink S/PDIF input. That appears crazy to me, but to Ayre, no. They've found their own road.

The experience left me doubting my ears. After I'd performed all the measurements of Ayre Acoustics' KX-R preamplifier ($18,500) to accompany Wes Phillips's review in our November 2008 issue, I spent a weekend listening to it. To my astonishment, the sound of my system with a Transporter D/A processor feeding the preamplifier was better than when the DAC fed the power amplifier directly. Through the KX-R, images sounded more tangible, and the sound was better focused, despite the signal's having been passed through not just another set of interconnects but also through the preamp's input and output socketry, switches, a volume control, printed circuit-board traces, and active and passive parts. Logically, you'd think that having nothing in the signal path would have less of a degrading effect than so many somethings. But no, that was not what I heard, much as I would have preferred otherwise.

Of the hundreds of product reviews I have written over the years, it is perhaps those of power amplifiers that present the hardest task in defining their worth. This is not because power amps are unimportant. As I wrote in my review of the MBL Corona C15 monoblock, in June 2014, "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." But because the amplifier's role is so fundamental, it can at first be difficult to determine a given amp's balance of virtues and failings. A paradox.

There was a period in the 1970s when many pop ballads that should have had understated arrangements instead turned grandiose and even maudlin. Take Gilbert O'Sullivan's sensational single "Nothing Rhymed" (a track that went deep for a pop hit, referencing famine, duty, and morality). Soon after the start, O'Sullivan's piano is overshadowed by a loud, saccharine string section.

Another example is "Lotte," German singer Stephan Sulke's portrayal of a dying love affair. The devastatingly wistful chanson is burdened by a mawkish orchestral track—the equivalent of glitterbombing an Edward Hopper painting.

Contrast this with Roberta Flack's definitive version of Ewan MacColl's "The First Time Ever I Saw Your Face." Apart from Flack's voice and her emotional delivery, the gently strummed guitar and quiet piano do all the heavy lifting. An unhurried double bass and a couple of minimally bowed string instruments leave swaths of negative space, helping to give her interpretation its hushed, reverent character.

I reflected on all this after spending several months with Balanced Audio Technology's REX 500 solid state power amplifier ($25,000), which has more in common with the Roberta Flack track than with the bombast of "Nothing Rhymed."

A quarter-century ago, when we were just getting into wine, my wife and I took a trip to Napa Valley. At one premium vineyard, we took a taste from the $20 bottle, then, for the hell of it, a taste from the $50 bottle. The first taste was nice; the second was alarming—an explosion of flavors, a gateway to sensory delights that we hadn't known could be had from a barrel of crushed grapes. We wobbled away, concerned that high-end wine might be a dangerous hobby.

Stereophile normally doesn't review audio systems. We review individual components. We've made an exception for the Bel Canto Black system because it deserves to be evaluated as such. It consists of three dense, almost identically sized cases of black-anodized aluminum. One, the ASC1 Asynchronous Stream Controller, is what in a conventional system would be called a "preamplifier." The other two, a pair of MPS1 Mono PowerStreams, would in a conventional system be called "monoblock power amplifiers."

International audio shows are a white-knuckle thrill ride. The moment I first entered one of the four colossal, cathedral-like "Halles" of High End Munich 2024, my brain short-circuited. Among the products that gripped my senses that weekend, the Brutalist allure of the BennyAudio Odyssey Turntable ($45,000) spoke to me loudest.
