Top-Notch DAC for Raspberry Pi

Looking to step up your DIY audio project with sound quality and great value? The Allo BOSS V1.2 has you covered. Featuring a unique implementation of the Texas Instruments PCM5122 DAC, this latest-generation DAC offers a dual RCA output. Compatible with Raspberry Pi 2 and 3 (models B and B+),  but independently powered and clocked, the BOSS streams music without all the noise that comes from dirty RPI power and jittery clocks. Once it's put together, you can build a high-end streamer or a multi-room home system.

Note: The base price is for the circuit board and a USB adapter cable. At checkout, you can add a black acrylic case with black standoffs or a clear acrylic case with gray standoffs to house the board (+ $13).

The Reviews Are In

Darko Audio calls it a “super-tasty, delicious Pi maker” and says, “As streaming starting points go, rarely do they come as compelling as—or as affordable as—the BOSS DAC back-strapped to a Raspberry Pi. Round ‘ere, such bang for buck equates to a sucker punch.” To learn more, check out this DIY Audio thread.
