Components listed here have been formally reviewed in Stereophile and have been found to be among the best available in each of four or five quality classes. Whether a component is listed in Class A or Class E, we highly recommend its purchase.

Each listing—in alphabetical order within classes—is followed by a brief description of the product's sonic characteristics and a code indicating the Stereophile Volume and Issue in which that product's report appeared. Thus the September 2012 issue is indicated as "Vol.35 No.9."

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."

When something called "high fidelity" assumed fad status during the 1950s, many manufacturers climbed on board by the simple expedient of adorning their last year's product with a high fidelity label. The Home Theater bandwagon is a little harder to jump on, because loudspeakers for use with television sets require something "ordinary" stereo speakers don't: magnetic shielding (or, more accurately, magnetic cancellation). Without it, placing the speakers within a few feet of a large-screen set does psychedelic-type things to the color (footnote 1). However, adding magnetic shielding, usually in the form of a second magnet glued to the rear of each loudspeaker's motor magnet, is the only thing that some loudspeaker manufacturers change before slapping a Home Theater label on last year's stereo speakers.
