Monoblock Power Amplifier
By John Atkinson
Classé Delta Mono

Canadian audio manufacturer Classé Audio was founded in 1980 by engineer Dave Reich and entrepreneur/audiophile Mike Viglas. The name “Classé” was a pun on the fact that Reich was a firm believer in an amplifier’s output stage operating in class-A, where the output devices never turn off (see sidebar). Though the brand was established with the 25Wpc DR-2, the first review of a Classé amplifier to appear in Stereophile, by Larry Greenhill, was of the later DR-3, in December 1985. This review had not yet been reprinted on the magazine’s website at the time of writing this report, but no fewer than 21 reviews of Classé products are available in our free online archive. These include the CAM-350 monoblock amplifier, which was reviewed by Brian Damkroger in January 2001 1 and has been used by Jon Iverson, AVTech’s self-described “web monkey,” as his long-term reference amplifier.

My own experience of a Classé amplifier dates from March 2011, when I reviewed the CT-M600 and CA-M600 monoblock amplifiers. 2 So positive was that experience that, when Editor Jim Austin asked me if I would be interested in reviewing Classé’s new third-generation Delta Mono amplifier ($21,998/pair), I didn’t hesitate to say “yes.”

First, some history Classé Audio became part of the Bowers & Wilkins Group in 2001, with Viglas staying on as chairman and the day-to-day running of the company being handled by branddevelopment VP Dave Nauber. (Reich had joined Theta Digital by that time; Viglas retired in 2010 and passed away in 2018.) In May 2016, B&W was acquired by EVA Automation; a year later, the new owner shuttered Classé’s operations in Montreal and all employees, excluding thenpresident Dave Nauber, were let go.

BRILLIANT CORNERS - I have a day job at a museum. One of my favorite things about working there is taking the elevator from my office down to one of the floors open to the public; I walk into the galleries through a discreet panel in the wall. This makes me feel like I'm in one of those horror-movie manors with a tunnel concealed behind a bookshelf. Sometimes I startle people, which I kind of enjoy.

EDITOR'S PICK - RECORDING OF THE MONTH

The record business was awash in money and power. Vinyl LPs were still five bucks, and while the pressings could be suspect, the music-buying public still snapped them up en masse.

The Butthole Surfers wipe out

REVINYLIZATION - Music's lunatic fringe drifts further out every hour. As it should. In this century, with computers playing an ever-larger role, music continues to fragment and become infinitely more varied. This splintering is either the essence of what keeps it relevant as an art form or something profoundly disturbing, to be hated and feared.

AURAL ROBERT - The least surprising story in music today is the inevitable passing of irreplaceable talent. Tenor saxophonist Benny Golson died at age 95 the day I finished this salute to another fallen star, Southern California singer/songwriter John David \"JD\" Souther.

PS Audio Aspen FR5 - LOUDSPEAKER

I remember the first PS Audio product: a simple phono stage. It was so simple - a passive RIAA eq filter flanked by a pair of primitive op-amps - that when the schematic was made public, I built one myself; I was in the midst of my DIY years. I thought it was, to use a word from that time, nifty.

TEAC UD-701N - STREAMING PREAMP, D/A CONVERTER

In Gramophone Dreams #88, I described the sound of TEAC's VRDS-701T CD transport as \"dense and precise in a way I had never previously heard from digital.\" I went on to explain, \"by dense, I mean there was a tangible corporeality effected by seemingly infinite quantities of small, tightly packed molecules of musical information.\"

Sonus faber Sonetto V G2 - LOUDSPEAKER

Here's a hard truth: A written review of a full-sized speaker any speaker, really-is, at best, semi-useful. We all listen differently, we have different musical tastes, our system electronics are different, and our listening rooms vary a lot. You will gain a general picture of a speaker's capabilities and foibles from John Atkinson's measurements, and I can tell you how the speakers sound to me, in my room. But that's it. You need to hear them for yourself before making a buying decision. The best I can do is tell you how my music brain felt when the speakers were in my house and making music.

STEREOPHILE'S 33RD ANNUAL - PRODUCT OF THE YEAR AWARD 2024

When Stereophile's Product of the Year Awards were first published, in 1992, we decided that unlike some other publications and their awards schemes, we would keep the number of categories to a minimum. That way, we would avoid what the late Art Dudley once described as the \"every child in the class gets a prize\" syndrome.

Moon 861 - POWER AMPLIFIER

It is unusual to begin a review with a detailed discussion of setup. But setup protocol for the Moon 861 power amplifier ($22,000 each), the top-level amplifier in the North Collection from Moon, which I reviewed bridged in mono, proved crucial to its sound.
