Designer Dr. Roger West got his first taste of electrostatic transducers many years ago during a stint with Janszen (remember the Janszen tweeter?). To realize the potential of the full-range electrostatic loudspeaker (ESL), he and Dr. Dale Ream formed a new company dedicated to ESL research and development. West describes this company, Sound-Lab Corp., as "the electrostatic speaker specialists."
There was a time, as recently as 40 years ago, when frequencies below 100Hz were considered extreme lows, and reproduction below 50Hz was about as common as the unicorn. From our present technological perch, it's too easy to smirk condescendingly at such primitive conditions. But just so you're able to sympathize with the plight of these disadvantaged audiophiles, I should tell you that there were two perfectly good reasons for this parlous state of affairs. First of all, program material at that time was devoid of deep bass; not because it was removed during disc mastering but simply because there wasn't any to begin with. The professional tape recorders of the day featured a frequency response of 5015kHz, ±2dBjust about on a par with the frequency performance capability of a cheap 1988 cassette tape deck.
While brushing my teeth this morning, it occurred to me that there are significant similarities between a toothbrush and a tonearm/cartridge. The bristles would be analogous to the cartridge and the brush handle to the tonearm. In either case it is the business end of the device that does all the work. The bristles track the contours of your ivories in search of hazardous waste deposits, while the cartridge tracks the record groove transducing wall modulations into an electrical signal. I think that this is where the old adage came from: "A used cartridge is like a used toothbrushnobody wants one!"
Stereophile: You are president of Esoteric Audio Research, a British manufacturer of tube amplifiers, and a world-renowned designer of tube equipment and output transformers. I thought we'd begin with a little background. Where were you born? What kind of education did you get to prepare you for a career in audio?
