The all-FET, class-A, B2B-1 phono preamplifier ($1749), made in the US by Liberty Audio, is beautifully built inside and out, and comes in a heavy-duty aluminum chassis with a baked-on crackle finish and a 3/8"-thick, black-anodized faceplate. The overall build quality and physical appearance suggest something that costs more than $3000, which is probably what it would cost were it sold through retailers and not factory direct. It comes with a two-week return policy.

PSB is a small, Toronto-based manufacturer that has been collaborating with Canada's National Research Council to try and take some of the guesswork, some would say magic, out of loudspeaker design.

The NRC, financed by the Canadian government, does basic research in many technological areas and makes its findings available to any firm wishing to use them. (Most other countries provide or encourage this kind of government/business cooperation. It is against the law in the US, to our great disadvantage.) The NRC's audio division, headed by physicist Dr. Floyd E. Toole, has devoted the last several years to the rather formidable task of defining, and assigning numbers to, the various aspects of loudspeaker performance that affect listeners' subjective assessments of their sound.

As the music swelled in the background, Humphrey Bogart leaned toward Ingrid Bergman and tenderly said, "Mnn mmmm mnn nnrm murrrmr."

Damn! I hate when that happens. I ran the laserdisc back and played it again, this time louder.

"MNN MMMM MNN NNRM MURRRMR," said Bogart.

When you think about it, the center channel is probably the most important channel—if you don't believe this, watch a movie sometime with the dialog speaker turned off and see how compelling the experience is. I mean, I like explosions, rocket launches, and train wrecks as much as the next guy, but what I really want from a video sound system is the words.
