Way back at CES 2014 (I know it was just in January) Diamond showed off their new Xtreme Sound 24bit 7.1 Channel Digital Audio Adapter, mercilessly abbreviated to XS71HDU. Heading into Q2 2014, theyre finally gearing up to launch the product with a target release window of late May.

As the name suggests, Diamonds latest supports true 7.1 HD audio output. Its compatible with Mac, Linux, and of course all modern versions of Windows. It requires a Core 2 Duo or AMD equivalent processor at 2.2GHz or faster, 10MB HDD space, 1GB of RAM, and an open USB drive and CD-ROM drive for the installation software.

Theyre fairly tame requirements for what the XS71 offers and interested audiophiles can head over to the official Diamond product page to read all of the specifications. The Xtreme Sound adapter will retail for $59.99. Check out some of the details below.
