"Something's coming, I don't know what it is, but it is gonna be great!"—Tony, West Side Story

While the Sharks and the Jets rumble in the consumer electronics playground, knife-fighting for supremacy in the next software go-round, in 1998 we're still living in the 16-bit/44.1kHz audio world, and will be doing so for the foreseeable future. Maybe your idea of audio bliss is listening to the equivalent of computing with a Commodore 64, but it's not mine.

Spectral X-Contamination: Problems in Op-Amp Chips

In high-end circles, the sonic repute of integrated-circuit op-amps (from "operational amplifier") is, at best, checkered. Of course, the expertise with which they are used and the parts they're used with can make all the difference. For example, my DIY preamplifier design, "AMP-02," published in Hi-Fi News & Record Review in 1989–90, and my earlier (1983–84) AMP-01 (footnote 1), I used the better IC op-amps of the time throughout. Both units were thought to outperform cost-no-object commercial units of the time that employed discrete transistors and even tubes, and only indicate what's possible.
