Audio Unleashed
This is Audio Unleashed: the world’s only totally unfiltered, freewheeling, fearless discussion about the latest events in the world of audio, featuring veteran audio reviewers Brent Butterworth and Dennis Burger. With decades of experience, a modest grasp of science and logic, and a marginal degree of financial security, they can tell the good from the bad, and the proven from the preposterous — and they’re not afraid to tell you what’s what.
