Introduction

Audirect is a Chinese company that specializes in portable digital analogue converters (DACs). They started with the Whistle and released the Beam recently. I would like to thank Audirect for the review unit of Beam. At the moment, you can purchase the Beam from Penon Audio or Audirect .
