BURLINGAME, California — Upon arriving at the California Audio Show, we spent a few minutes ogling the Ferraris and Maseratis in the parking lot.

Little did we know that once we walked inside, we'd see stereo systems twice the price of one of those fancy sports cars.

The CAS — far removed from the massive, mainstream industry trade shows — is organized by Constantine Soo, publisher of the high-end audio site Dagogo.com. This is Soo's second year running the show, which is the largest on the West Coast, boasting around 3,000 attendees over a weekend in mid-July.

On display were hand-built monoblock tube amps, omnidirectional speakers, gas plasma drivers, 6-foot-tall subwoofers and laser-guided turntables — objects made for people with the ears, the mindset and the trust fund to appreciate such things. You could trade reel-to-reel tapes with other collectors, or join the debate in the hallway about which test tone is most appropriate for calibrating your digital transport.

Soo is quick to stress that almost everything at the show is for two-channel stereo playback, not for watching movies in surround sound.

"Home theater stuff is for everyone in the family," he says. "This stuff is for the fanatics and the audiophiles who have a dedicated room in their house just for music listening."

A quality preamp is a necessity for bringing out the dynamics in a recording, and you'd be hard pressed to find a component better — or better-looking — than Einstein's "The Tube." This $18,400 unit from the German company uses 19 vacuum tubes to discretely power as many as five audio sources.
