Another contender emerges among entry-level separates.

In case you hadn't noticed, the bell has rung, and the blows are flying in the $3,000-to-$5,000 range for electronics systems (i.e., preamplification, processing, and amplification). It's easy to characterize this as a melee between receivers and separates, which is a key component of what we're seeing at this price level. Receivers are sounding better and getting more expensive; separates are getting more user-friendly, offering more features, and dropping in price.

Adcom first appeared on the technophile radar in 1979, with the introduction of the GFA-1 power amplifier—the beginning of a long series of affordable, high-performance audio products. Then based in New Jersey, Adcom hit its stride in the mid- to late 1980s with its GFA-555 and GFA-565 power amplifiers and GTP-555 and GTP-565 preamplifiers, all of which were well received by reviewers and music lovers alike. Solidly built, extremely reliable, and musically satisfying, these products earned Adcom a reputation for quality that reviews of its more recent products continue to confirm.

The Canadians and the Brits are at it again.

If you know your history, then you already know that the Canadians and the English can do some good things when they get together. While we were taking care of our business down at Utah and Omaha, the Canadians and the Brits were giving the Germans a pretty good working-over of their own up the beach at Normandy. They even teamed up rather effectively against us during the American Revolution and War of 1812, managing to hang on to Canada despite our various efforts to take it and, in the process, preserving one of England's last real toeholds in the New World.

In today's hotly contested home theater market, the big consumer-electronics manufacturers are grabbing an increasingly important slice of the pie. Their new, big-boned receivers&mdash;with prices to match&mdash;approach (or sometimes exceed) the performance of most separates. The competition is fierce, with those mega-corporations using their marketing clout, engineering expertise, and production efficiency to built better products, but smaller companies can still compete. They're fighting back with separate pre-pros and power amps that trade on their traditional strength: sound quality.

Close to the edge.

I'm constantly amazed by the steadily improving sound of real-world-priced components, but it's fun to see how far mind-bogglingly fantastic high-end electronics have come. Yes, I have to admit that there's a certain amount of poseur gear that sports nosebleed pricing but doesn't really deliver sound that's much better than everyday good stuff. Have no such worries here, though. Anthem's Statement D2 surround processor and P5 amplifier are the real deal. Even by high-end standards, their capabilities are inspired.

Price: $3,500 At A Glance: Enormous power output • Remarkably compact • Class D

Class D amplification has a narcotic-like hold on the audio electronics industry. These switching-mode designs mesmerize with a dazzling array of advantages: high efficiency, high power output, low weight, compact dimensions, and depending on implementation, enormous cost savings.

The Stage One is Aragon's second-generation surround processor, replacing and retiring the original Stage. The Stage One combines a strikingly machined front panel with the latest thinking in surround processing, including no processing at all for us vinyl buffs. And in a concession to those who think there might still be something on the public airwaves worth listening to in this ClearChannel world, the Stage One also throws in an AM/FM tuner. Visually, the robust 5-channel Aragon 3005 and 2-channel 3002 amps share the Mondial-inspired "M" design with the Stage One.

A few years and a publication ago, I reviewed Arcam's FMJ AV8 controller and was frankly bowled over. At $5k I thought the AV8's detailed and dynamic sound made more expensive controllers a much harder bargain than before, and I recommended and continue to recommend that controller to anyone shopping in that price range. Enter Moore's law.

Though it's a relatively small company, UK-based Arcam has long been known to place heavy emphasis on R&D. When I visited the factory a few years ago, I was shown some of the impressive development work then in progress. This effort, said by Arcam to run well over $1 million, has resulted in some impressive new products, including the FMJ AV8 preamplifier-processor and its companion FMJ P7 power amp.

THE VERDICT
The days of looking down on Class D amps are over.

Two and a half years ago, I reviewed my first ATI amplifier, and to say I was impressed would be an understatement. The ATI Signature AT6005 five-channel amp set a new benchmark for its designer, Morris Kessler—to the point where he put his John Hancock on the faceplate.

Last year, S&V editor-at-large Bob Ankosko sat down with Kessler to talk about his design philosophy over the years, and the subject of Class D amps was broached. Kessler mentioned that his current designs were all Class A/B, but he was following the developments of Class D very closely—though the initial efforts in this area didn’t meet his high standards because frequency response varied greatly as the impedance of the speaker changed. He hinted at the time that he may have finally found a Class D solution that he could deem acceptable, which turned out to be the latest Hypex Ncore modules.

THE VERDICT
This amp never broke a sweat driving my 4-ohm speakers at insanely loud levels.

There are quite a few people in the audio world who have become household names, at least among audiophiles. I’m talking about legends like Paul Klipsch, Amar Bose, Saul Marantz, Henry Kloss, Bob Carver. But these aren’t the only influential contributors to the business and history of hi-fi. Among the lesser-known audio icons is Morris Kessler, the founder of ATI.

For the benefit of those who find it difficult to keep straight all the different manufacturers whose names begin with "Audio," Audio Refinement is the brand name of YBA's affordable line of electronics. YBA itself&mdash;if you're really out of the loop&mdash;is probably the best-known manufacturer of audio equipment in France. YBA is a family business, the initials standing for the name of the designer, Yves-Bernard Andr&#233;, whose wife, Ariane Morin, is the company's CEO.

At first sight, the corporate-designed, picture-perfect streets of Boulder, Colorado, silhouetted against the breathtakingly beautiful but dry purple-brown Rockies, reminded me of a mall with its lid ripped off. Then again, maybe it was the lack of oxygen. Ski? Me and my politically incorrect, gas-guzzling Lincoln Town Car rental (unlike the perfectly acceptable gas-guzzling SUVs everyone in Boulder drives) were in town for only a short visit, mainly on business unrelated to <I>SGHT</I>. But I had a day free for a little sightseeing and an interesting visit with Charlie Hansen, president and owner of Ayre Acoustics. I was scheduled to review Ayre's newest multichannel amplifier, and this gave me the chance to learn more about the product and the company.
