Solid State Power Amp Reviews

Some of the old audio names, such as Eico and Pilot, are gone. Others—Fisher, AR, KLH, H.H. Scott, etc.—have been rendered meaningless by corporate mergers and acquisitions. Yet more than 50 years after their founding, McIntosh and Marantz, arguably the two most prestigious names in American high-quality audio electronics, survive. The products they make today are probably closer in spirit to their original classics of half a century ago than at any time since the early 1970s.

We all have biases. The trick is knowing your biases so they don't get in your way. Mine are pretty obvious. I don't like "fussy" gear that demands special care and feeding. I'm lazy—I want to just turn stuff on and begin listening. Perhaps that's why I have a positive bias toward Nelson Pass's designs. They're reliable, untweaky, and usually sound good.

I think every audio reviewer hopes for a surprise—when a good, but not outstanding, product is refined by the manufacturer into something special. The review then becomes an exciting discovery, reaffirming the pleasure one takes in good audio, and in listening to music being reproduced as it should be. It makes the listening exciting and the writing easier. The Classé Fifteen solid-state stereo amplifier is just such a surprise.

Boulder Amplifiers, named after the Colorado town where the company has resided since its founding 23 years ago, makes some of the most elegant-looking solid-state amps around. Chassis are anodized, aircraft-grade aluminum with rounded edges, machined and finished in-house. The two models reviewed here, the 810 line preamplifier and the 860 power amplifier, each have a sleek, compact build—stacked atop each other, the two stand just over a foot high—owing to extremely efficient packing of the circuitry inside. These are the company's "entry-level" electronics, but there's nothing cheap about them—the preamp retails for $6900, the amp for $8500—and for all their economical size, they look like luxury goods as well.

There's always a certain amount of jockeying for position at the very top of the High End. Every few months, a new star burns brightly, getting all the attention. While the constant turnover at the cutting edge helps to define the state of the art, audiophiles should keep their eyes on the longer term. It's a company's track record—examined over a period of years—which defines its position in the market and the credibility of its products.
