Welcome back! In this episode, Darren, designer of an amplifier that TAS just named "2021 Product of the Year (huzzah!)," takes us patiently and steadily through a basic concept involving operational amplifiers, or amps-on-a-chip, explaining how feedback is heavily used in many modern op-amps to broaden what, in some cases, is a staggeringly low bandwidth to begin with. Don't worry - if Duncan can understand this by the end of the show, so can you. Don't miss more questions and a surprising yet completely amazing album recommendation to round out the show.
