In 1979, I visited Philips Electronics' renowned Research Center in Eindhoven, Holland, to examine a prototype of what would eventually be called a compact disc player. In 1989, I returned to the Eindhoven lab to witness the birth of the first sigma-delta DACs, which eliminated the problem of large linearity errors at low recorded levels in resistor-ladder DACs.

A few months ago, a friend asked me to recommend a record player. This friend knows and loves music as much as I do; when he visits, we spend our time drinking wine and listening to records. Last time, it was Scott Walker, Fela, Joni Mitchell, Jacques Brel, Burzum, and both glorious sides of The Chronic.

"How much do you want to spend?" I asked cautiously. His answer: $500, tops.
