Based in Songnam City, South Korea, Allnic Audio was founded in 1997 by Kang Su (“K.S.”) Park. Park has always been keenly interested in music and electronics—his older brothers, both electricians, taught him the basic principles of electronics at an early age, and soon he was building his own audio components. However, according to Park, at the time neither Korean culture nor his parents valued the electronics trade. When he attended university in Seoul, he studied for and received a degree in French language studies.

Reviewers' Choice In May 2020, when MSB Technology announced their S202 stereo amplifier ($29,500, all prices USD), I thought it a perfectly sized power amp. I could move its 90 pounds myself, and its dimensions of 16″W x 7″H x 19″D meant that it could fit many places, including the shelf of an average-size, high-end audio rack. Still, I could see, even in the photos, that it was a substantial machine. Its contoured aluminum case and chassis—in this model they’re the same thing—were obviously the results of lots of CNC milling, and inside, its jewel-like parts and layout made clear that the S202 was a lot more than a pair of tiny class-D amps rattling around inside an otherwise empty box.

In 2011, Classé Audio introduced the CP-800 preamplifier-DAC ($6500, all prices USD) to replace the well-received, analog-only CP-700 preamplifier ($8000); both models are now discontinued. In 2013 I reviewed the CP-800, our editorial team named it a Reviewers’ Choice, and I made it my reference preamplifier. The CP-800 remained largely unchanged until late 2016, when it, too, was discontinued.

Reviewers' Choice To many audiophiles, this one included, luxury loudspeaker maker Estelon has largely been a mystery. What I knew about Estelon before this review—and I follow the upper end of the hi-fi market closely—was entirely superficial: They’re based in Tallinn, Estonia, in northern Europe; before COVID-19, they displayed their wares at Munich’s annual High End show; the shapely forms of their speakers are often described as elegant; and those speakers are not inexpensive.

Reviewers' Choice A little less than two years ago, I reviewed Audio Research’s Reference 6 preamplifier ($15,000, discontinued; all prices USD). Little more than a day of listening later, I’d decided I wouldn’t be sending my review sample back, and ever since, the Ref 6 has been my reference preamp. Asked to review the Ref 6’s successor, the Reference 6SE ($17,000), my answer was a no-brainer: Yes.

It’s not imperative for me that an audio component be visually flashy or fancy. I still love the clean, classic simplicity of, say, the basic burnished metal faceplate of a vintage Conrad-Johnson or Audio Research model—no knobs or buttons other than a power switch. That said, there’s something about watching the myriad meters of my reference system of McIntosh Laboratory amplification components dancing in a blue glow—my experience of the sound is enhanced by the system’s visual appeal.

Reviewers' Choice In December 2017, I reviewed and then bought Esoteric’s one-box Grandioso K1 SACD/CD player and digital-to-analog converter ($31,000, discontinued; all prices USD). That’s a lifetime ago in the fast-paced world of digital audio, but some things haven’t changed—for one thing, as evinced by the K1’s successor, the Grandioso K1X ($36,000), Esoteric is sticking with the format of 4.75″ shiny silver discs. From the company known for having virtually perfected the SACD/CD transport, that’s no surprise.

Reviewers' Choice Mike Viglas and David Reich founded Classé Audio in 1980. Their first product, the DR-2 class-A power amplifier, quickly gained notoriety for its ability to convincingly drive loudspeakers to unexpectedly high volume levels despite its diminutive power-output specification of 25Wpc. To this day, the success and sound quality of the DR-2 serve as hallmarks for every Classé product since.

In his inimitably matter-of-fact fashion, Magico’s Alon Wolf once told me that “We make loudspeakers, not furniture.” The statement seemed to imply that, for him, form must always follow function. I suspect that the philosophies of most discerning audiophiles are similar. That’s one reason why ultra-high-end systems are often found in dedicated rooms replete with treatments, cable lifters, and fastidious attention paid to ensure that those systems are performing optimally, no matter the imposition. Everything else is subordinated to the pursuit of maximum sound quality.

When I unboxed Vinnie Rossi’s new L2i Signature Edition integrated amplifier-DAC, two things stood out: 1) It’s good-looking and extremely well built. 2) I didn’t see how it could be worth $22,490 (as reviewed, with optional DAC module; all prices USD). It wasn’t until I’d spoken with founder-owner-designer Vinnie Rossi himself that I began to appreciate what I’d been sent. (See my profile of Rossi and his company.)
