LATEST ADDITIONS

As strongly as I believe that the listening experience is the most reliable method of judging the quality of audio equipment, I've been biased against single-ended tube amplifiers because of their quirky measured performances. Without having heard single-ended under good conditions—much less living with an SE amplifier—I had concluded that many listeners must like them because they're euphonically colored by large amounts of low-order distortion and impedance interactions with the loudspeakers. SE amplifiers seem to be a departure from the goal of making the electronics transparent. Moreover, the range of loudspeakers suitable for SE amplifiers is so restrictive that I wondered why anyone would bother with these underpowered distortion-generators. I had fallen into a trap that I've repeatedly railed against: drawing conclusions without firsthand listening experience (footnote 1).

Let me take you back some 40 years to the mono days of the early 1950s. It's unlikely that the minimonitor genus of loudspeakers, of which this French JMlab is a prime example, would have survived back then. There was the practical problem of available amplifier power. The average amp could squeeze out no more than 10 to 15W into an 8 ohm load—far less power than the typically insensitive minimonitor demands for adequate dynamic headroom. But that in itself would not have sufficed to displace the minimonitor from the marketplace. After all, "high-power" amps (50-watters) could be had at a price.

<I>Cary Audio Design founder Dennis Had is largely responsible for popularizing single-ended amplifiers in America. Since appearing on the scene in 1989, Cary Audio Design has forged its own niche in the high-end audio industry. I spoke with Dennis Had about how he got started building amplifiers, and why he's so committed to single-ended triode designs.</I>

The Sears guy came to our basement the other day to check out the water heater. Staring at the walls of LPs and tiptoeing through the piles of CDs strewn on the floor, he exclaimed, "What the heck are you? A disc jockey?" So I told him.

Until just recently, only companies known primarily for their surround-sound processors were producing the most advanced&mdash;and most expensive&mdash;Home Theater products. No longer. It was inevitable that traditional high-end audio manufacturers would begin producing equipment for this fast-growing market.
