TO BE … OR NOT: Bi-amping?

PAUL MCGOWAN … There once was a day when power amplifiers struggled. The mainstays, tube amplifiers, couldn’t handle low frequencies well but had immaculate highs.

VANDERSTEEN: Richard Vandersteen: Keep on Truckin’ – by Ken Kessler

First published in 1988 Richard Vandersteen doesn’t look like a typical loudspeaker designer. True, he wears glasses, but his presence suggests a longshoreman or somebody who’d be played by Gene Hackman. And sure enough, he tells you in a quasi-Dukes of Hazzard drawl that he’s been a construction worker, plumber, truckdriver, and electrician. Electronics had […]
