All Metal, Custom Engravable, USB Type C

Atom DAC 2 helps your get the most out of your JDS Labs Atom Amp 2 or Atom Amp+, ensuring that your amp delivers its rated power. Equipped with USB Type C and TOSLINK inputs, Atom DAC 2 runs on our latest upgradeable XMOS-based firmware, supporting UAC2 and UAC1 fallback*. Its subtle light ring glows during use, automatically powers down during periods of inactivity, and wakes up instantly and silently. Additionally, Atom DAC 2 operates cooler due to a more efficient I/V stage, and its new aluminum enclosure is custom engravable!
