<I>Revolutionary</I> is a word that's tossed around all too lightly in the world of audio. The understandable impulse to tout every new development as a quantum leap forward in sound reproduction has made it difficult to sort out the evolutionary from the truly groundbreaking. And there's not that much left to do in amplifier design that is worthy of being described as "revolutionary," or so it seems. Vacuum-tube circuitry has been thoroughly understood since the late 1940s, and 40 years of development of solid-state has rendered it, in its finest implementations, a worthy competitor and alternative to the venerable tube.

When it was suggested that I call in on speaker manufacturer RBH Sound during a planned <A HREF="http://www.stereophile.com//asweseeit/470/">trip to Utah</A> in the fall of 2001, my response was "Who is RBH?" To my embarrassment, the speaker company had not popped up on my radar screen since it was formed in Los Angeles in 1976. However, I had certainly heard some of the speakers they had manufactured for other companies, most notably the McIntosh models of the early 1980s, with their line arrays of dome tweeters.

Rarely has the debut of a new loudspeaker company and its inaugural model created as big a buzz as did Lumen White and their Whitelight speaker at the 2001 Consumer Electronics Show. Driven by Vaic tube amplifiers in one of the larger corner rooms at the Alexis Park Hotel, the big Whitelights had a look and a sound that attracted continuous crowds. Of the questions among audio cognoscenti that I overheard at the end of each day, two of the most common were "Hey, did you hear those Lumen Whites?" and "What? Can you speak louder?"
