"A guy's gotta carry a cow across a river. He's not strong enough, of course, so the only way he can do it is to cut the cow into pieces, carry them across a few at a time, and re-assemble the beast on the other side. When he's finished, he's got a cow on the other side of the river, but it's not exactly the same cow."

It was late May 2002 and I was about to leave the Free Republic of Bay Ridge, Brooklyn, for the high-class hallways of the New York Hilton and Home Entertainment 2002, so I could file daily reports for www.stereophile.com. As he was giving me last-minute instructions, webmaster Jon Iverson said, "I don't know whether or not you followed Hervé Delétraz's articles on building his amplifier, but he's going to have a sample at the Show. You should drop in and check it out. It sounds kind of interesting."

The Canadian audio industry has been mounting a challenge to other high-end manufacturers over the past few years. Ask any audiophile about Canadian audio manufacturers and chances are that he or she will have no trouble rattling off a string of respected names—Classé, Museatex, Sonic Frontiers, Mirage, PSB, Paradigm, Energy. And Bryston.

The "Reference" designation is thrown around a lot in the world of perfectionist audio. It's most often used to elevate the top of the line to a higher perceived status. Occasionally, as in the case of the VTL TL-7.5 line stage that I reviewed in October 2003, it genuinely denominates a component that is clearly superior to its competition in most aspects of performance.

Non-audiophile friends and relatives raised their eyebrows when they saw the Classé Omega Omicron monoblocks. Not only is the Omicron more expensive than any other amp I've used; at 108 lbs, it's heavier than some of the speakers I've used. The Omicron is Classé's next-to-top-of-the-line amp in its Omega series, but is still definitely a "statement" product. Brian Damkroger reviewed the Omicron's big brother, the Omega Mono, in the July 2003 Stereophile. I refer you to that review for a more detailed description of the Omicron's basic circuitry.

One of the highlights of recent Consumer Electronics and Home Entertainment shows has been the demonstrations of sound quality put on by Australian amplifier manufacturer Halcro with Wilson Audio loudspeakers. At my first exposure to one of these demos—described in my April 2002 "As We See It"—enormous dynamic range was coupled with a grain-free presentation and almost holographic stereo imaging to produce a breathtaking sweep of sound. Paul Bolin reviewed Halcro's dm58 monoblock in October 2002, and that amplifier was subsequently voted this magazine's "Amplification Component of 2002" by our reviewers.

It's true—you never forget your first love. And no, I'm not talking about little Jackie Lynn Neeck in my second-grade class when I was seven years old. I still remember her, almost as vividly as I remember my first encounter with a fantastic stereo system, and therein hangs a tale.

Consider the plight of solid-state muscle amps. Often derided as brutes lacking sophistication or subtlety, particularly by the SET set (ie, fans of single-ended triodes), these powerhouses are taken for granted and often, like Rodney Dangerfield, they get no respect. And once upon a time, the stereotypes were true. Every veteran audiophile has at some time heard an immensely powerful transistor amp that had the soft sonic allure of a sheet of sandpaper, a lumbering oaf of a component with nothing whatsoever to recommend it save for a bulging set of mighty moose muscles.

Pass Laboratories' X amplifier series represents the efforts of designer Nelson Pass to prove that simple linear amplifier topologies can be scaled to provide high-quality audio performance at very high power levels. The handsome X1000 monoblock under scrutiny here, the largest and most powerful amp in the Pass stable, makes 1000W into 8 ohms and a mighty 2000W into 4 ohms. The amplifier has no global negative feedback, and only two gain stages: the front-end provides all the voltage gain and feeds a high-current follower stage.

The story of New Acoustic Dimensions, aka NAD, begins in the late 1970s. The company was founded as a dealer distribution collective to design and market reasonably priced serious high-end gear to cost-constrained audiophiles. By eliminating needless features and focusing manufacturing in low-cost production facilities, NAD has successfully delivered audiophile-quality gear for 20 years at prices little more expensive than mass-market department-store schlock.

As technology develops, things get more and more complicated. With every update of Windows, the program offers greater flexibility, but runs slower and makes greater demands on hardware. Automobiles have become so complex that only the most highly trained mechanics are able to fix even a minor malfunction. Surround-sound processors come with inch-thick owner's manuals.

For me, the iconic Adcom power amplifier was the GFA-555. As an aspiring audiophile, I was deeply impressed with Tony Cordesman's review in Stereophile in 1985 (Vol.8 No.4). That did it! After years of kit-building and doing it myself, the '555 was the first factory-built amp that I wanted and could afford. Over the years, I changed speakers several times, and even added a fully regulated power supply to the '555, but it never balked. At the end of its tenure at my house, it had been demoted to my third-string backup; today it's making someone else tap his toes.

For better or for worse, appearances can make a profound first impression. Think of the bold, muscular curves of an Audi TT coupe, the planes and facets of a Lamborghini Murcielago, the sleek lines of a Gulfstream jet. In these vehicles, function and art are combined with smooth facility and perfect aesthetic balance.
