Power Amplifier Reviews

Power amps get little respect in the home theater world. They're the heavy, black (or silver) boxes that sit somewhere in the dark, serving your speakers with a generous supply of power.

After the parade of international system mates that we've had in every other installment of this column recently, we finally settle into a system whose parts share their nation of origin. Don't be too quick to assume that it is the United States or Japan I speak of—this month's system hails entirely from merry old England. This isn't terribly surprising, but it does give me an opportunity to say a few things to our friends across the pond that I've been meaning to say for a while, such as: Sorry about that whole revolution thing (although I don't really mean that sincerely), and thanks for the Rolling Stones, Lord Stanley (who gave us the Stanley Cup), and Elizabeth Hurley—in no particular order, of course.

My curiosity was naturally piqued a few years ago when I heard that Parasound was going upscale with their look. This was a company that had become virtually synonymous with performance plus value, facilitated somewhat by forgoing aesthetic flair, and I wondered where the decision to go uptown with the finish in the Halo line would lead. The first good sign was the Halos' higher price tags. It costs a lot more to make boxes look that good, and this told me that they weren't taking resources away from performance to do so. What ultimately satisfied my curiosity, though, was how good the Halo models sounded. Yet, there are still those who want Parasound performance, have less to spend, and don't mind—or maybe even appreciate—Parasound's rugged, utilitarian old style. The New Classic line is exactly what they're looking for.

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—with prices to match—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.

Once upon a time, audiophiles used to get very excited about power amplifiers. They would obsess about the minutiae of an amp's sonic character and its ability to successfully drive 2ohm loads. Times change. Now amplifiers are among the least sexy components in a home theater. Most videophiles would concur with the concept that amplifiers should be heard, but not seen. Within the new world order of home theaters, amplifiers have been relegated to a supporting role.

Most power amplifiers are primarily differentiated by their size and color. Eventually, even an amplifier fetishist grows weary of digging for the minute variations that make each amplifier special. Perhaps that's why it's so refreshing to discover an amp that embraces some truly unique new technology. Bel Canto, a small company located in darkest Minnesota, has managed to find a way to manufacture a digital amplifier, dubbed the eVo2, whose performance rivals that of more conventional analog designs.

Home theater in 2004 is like America in the 1950s, with a middle class that has steadily been building momentum and now finds itself in the midst of a major breakout. The same philosophy of the good life at a better price that spawned a culture of suburbs and credit-card debt in the '50s is spawning an unprecedented emergence of high-end home theater components at mid-level prices in the '00s.
