It's essentially the bible of tube audio design.<BR><BR>EDIT: Well, a 200 level book might be a bit TOO basic, since they focus more in circuit analysis, not design.

In the upper echelon of analog playback, where $10,000 turntables are considered entry points and the price of a reference-grade phono cartridge rivals a used car, the EAT E-Glo 2 arrives with a very ...

A class-D puts out a pulse-width modulated (PWM) signal instead of the typical class-AB amplifiers linear signal The PWM signal contains the audio signal and the PWM switching frequency plus harmonics ...

The biggest name in portable hi-fi players just teamed up with one of the most respected brands in in-ear monitors.
