Although one of the most innovative firms in the audio electronics field, the David Berning Company seems determined to keep as low a profile as possible. The company advertises little, does not actively seek out new dealers, and seems content to let potential customers seek it out, as though to say "Okay, here's my product, take it or leave it." Thus, even though both Stereophile and The Absolute Sound, in a rare outbreak of agreement, a couple of years ago declared Berning's TF-10 to be one of the best preamplifiers available, most serious audiophiles are still unaware of the Berning Company's existence. Perhaps the EA-2100 will change that.

This is an electrostatic column speaker, 6' tall and costing $6000/pair. An integral, fan-cooled amplifier is located in the base. The 2SW is said to cover almost the entire frequency range and is based on a patent, number 3,668,335, issued to manufacturer/designer Harold Beveridge on June 6, 1972. Internal acoustic lenses in front of the electrostatic panels widen the speaker's dispersion: In the Beveridge literature, it says "This 6-foot high device consolidated the entire frequency range into a vertical line source, and uniformly disperses it over a horizontal pattern, 180 degrees wide. The beaming characteristics of the high frequencies are ingeniously translated into the same dispersive pattern as the low frequencies, creating a perfectly balanced cylindrical sound wave front."

The Bose 901 has created more of a stir in audio circles than any other loudspeaker we can think of, with the possible exception of the original Acoustic Research system. Much of the 901's popularity is attributable to Julian Hirsch's rave report in Stereo Review, and there is no doubt but that Amar Bose's compellingly convincing ads had their effect, too. But these things alone could hardly account for the 901's popularity.

"As We See It" in the Stereophile issue dated Summer 1968 (actually published in 1970) noted the idealistic, glowing claims about how four-channel sound could put you right in the concert hail, but urged readers to wait before buying, to see whether quadrisound would indeed bring higher fidelity. We predicted it wouldn't—that whatever the potential of quadrisound (footnote 1), it would not be used to increase fidelity, but rather to play ring-around-the-rosy with music.
