xDuoo MU-603 Bluetooth DAC and Tube Pre-Amp

The xDuoo MU-603 is a Bluetooth preamp and DAC combo that delivers a modern feature set in a handsome desktop package. The preamp side is powered by a single 12AU7 preamp tube to add organic sweetness to your sounds—and because xDuoo has included a cutout in the metal chassis to expose the tube, you’ll always see why your audio sounds so good, too. The DAC side of the equation is powered by an ES9018K2M conversion chip that delivers an impressively low 100 decibels of signal-to-noise ratio for clean, detailed sound. And thanks to high-end components and an enthusiast-grade approach to capacitance design with gold-plated output ports, the MU-603 will work flawlessly from start to finish. The wireless transmission is controlled by a Bluetooth chip with Bluetooth 5.1 compatibility with support for SBC, AAC, and Qualcomm aptX codecs. It all sits in a sleek little desktop box that merges modern minimalism and all-metal industrial design for a DAC/preamp that look s as great as it sounds.
