Barrie, Ontario, about an hour's drive from Toronto, with a population of about 130, 000, is not a city that I associate with the design and manufacture of high performance audio equipment. It doesn't have even a single "real" audio store, just Best Buy, etc. But, as I found out at SSI 2010, Barrie is the home of McAlister Audio, maker of the OTL-195 monoblock amplifier and a prototype preamp. The designer is Peter McAlister, who produced his first prototype output-transformerless power amp ten years ago. The OTL-195 puts out 150W, and appears to be a very sophisticated design: fully balanced, able to drive 4 ohm loads, a circuit that tracks the signal level in the driver stage and modulates the control grids of output tubes, and various other circuit refinements. The OTL-195 is hand-built by Peter McAlister himself, and utilizes high-quality parts. The price is $8500/pair. As I mentioned in the blog posting below, the King Sound Prince IIs sounded great driven the McAlister OTL-195s.

Shows like SSI are about the cutting edge in audio, with the latest and (purportedly) greatest on display and demonstration. Given this, I always get a kick out of spotting a piece of equipment that just does not seem to belong in such august company. This Sanyo JCX 2600K stereo receiver is from another era—circa 1978–1981 according to the ever-helpful Google search. Looks like it's in great shape. I spotted it on a shelf in an area of the show where they were setting up racks of LPs for sale. What was it doing there? I have no idea. Wonder how it compares sonically with the latest-and-greatest?

"Are You a Sharpener or a Leveler?" was the title of my "As We See It" in the February 2009 issue. The terms sharpening and leveling come from work in the field of perception by the early Gestalt psychologists, sharpening referring to the exaggeration of perceived differences, leveling to the minimization of those differences.

A compact horn loudspeaker. Isn't that an oxymoron, like jumbo shrimp, or military intelligence? From such venerable speakers as the half century-old Altec Voice of the Theater and the Klipschorn, as well as more modern examples like the Avantgarde Acoustic Trio, horns have always been big. The original Avantgarde Uno was the smallest speaker in Avantgarde's line, but it was still visually imposing, with a big horn midrange on top, a horn tweeter below that, and a powered sealed-box subwoofer at the bottom. (I reviewed the Uno 2.0 in Stereophile in August 2000, Vol.23 No.8, and the Uno 3.0 in August 2002, Vol.25 No.8.) The Uno and its siblings, the Duo and Trio, are perhaps the antithesis of the in-wall loudspeakers beloved by interior designers. These speakers do not fade into the background—not visually or sonically.
