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.

"The only tubes that I want to see in my household are...the picture tube in my TV and the magnetron in the microwave oven," a Glendale, CA, reader recently wrote, and I guess his feelings reflect those of many when confronted by a supposedly "obsolete" audio technology. Forty years after the invention of the transistor and 20 after the widespread introduction of solid-state amplifiers (footnote 1), it must come as a shock to readers of the mass-market "slicks" that not only do a number of American manufacturers manufacture amplifiers and preamplifiers using tubes, but some of those companies—Counterpoint and Audio Research in particular—are among the more successful. It is the Classic 60 power amplifier from Minnesota-based Audio Research that is the subject of this month's lead-off equipment review.

Warning to Purists: Despite certain qualities about the ESL-63 speakers which you will probably like, Quad equipment is not designed primarily for audiophiles, but for serious-music (call that "classical") listeners who play records more for musical enjoyment than for the sound. Quad's loudspeakers do not reproduce very deep bass and will not play at aurally traumatizing volume levels, and Quad's preamplifier is compromised through the addition of tone controls and filters, all for the purpose of making old, mediocre, and/or worn recordings sound as listenable as possible.

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—and most expensive—Home Theater products. No longer. It was inevitable that traditional high-end audio manufacturers would begin producing equipment for this fast-growing market.

It was back in the mid-'70s that David Berning made a name for himself in the Baltimore-Washington area as an avant-garde designer—someone with a truckload of fresh ideas about tubes. At the time, though Audio Research was starting to crank out pretty decent amplifiers, tube design was pretty much reduced to a rehash of the Williamson circuit and the Dynaco mod of the month.

"Who Stole The Bass?" asked Anthony H. Cordesman, writing about minimonitors in the April/May 1987 Stereophile (Vol.10 No.3). And for the designer of a box loudspeaker, the fundamental design decision, at any price level, is how much bass extension to aim for. It will always be possible to design a speaker with extension down to 20Hz, but will the result be musically and commercially successful? Will the designer end up with a speaker hypertrophied in that one area at the expense of every other? Will, indeed, the result be feasible technically? For example, for a given cabinet volume, gains in low-frequency extension have to be balanced against corresponding drops in sensitivity, and it is quite possible that to go for 20Hz extension will result in a 60dB/W/m sensitivity, equating with a speaker that only plays extremely quietly, and thus of no use to anyone.

The Sound-Lab electrostatic loudspeakers are legendary. Many serious audiophiles have heard of them, and rumors of their existence abound in audio circles. But, like gnomes, UFOs, and poltergeists, Sound-Lab loudspeakers are sufficiently hard to find that it is sometimes difficult to prove to skeptics that they exist at all. Well, I can now report that they do. As proof of this contention, I can point to the two which are actually occupying solid, tangible space in my listening room at this very moment. I have even taken a photo of them, which will be published along with this report if they leave any sort of an image on the film emulsion. (Many such apparitions do not!)
