AMB Laboratories γ2 (Gamma2)

"The γ2 (gamma2) is an extension and upgrade to the γ1 DIY stereo digital-to-analog converter (DAC). It builds on γ1's modular idea, and pushes the concept far into the high-end. Designed for the compact, attractive and sturdy Box Enclosures B2-080 series extruded aluminum casing, γ2's tightly integrated packaging makes it ideal for home and portable use, such as computer audio, CD/DVD players and digital media players."
