Key Features
Shrinking high-performance audio into a desktop-friendly package, this is a full-fledged dual monaural DAC.
The UD-301-X is a USB DAC in the Reference 301 range, with a low-profile and small footprint that comfortably fits into the smallest spaces on desktops. Supports the playback of DSD128 and PCM 192 kHz /32-bit content from PC/Mac and features an improved analogue audio stage delivering excellent sound quality to your existing hi-fi system.
In addition, an innovative CCLC headphone amplifier circuit allows you to use the UD-301-X as a high-grade, standalone headphone amplifier as part of a minimalist desktop system, comprising which a computer, headphones and the UD-301-X.

A 215mm width and 238mm depth creates a footprint that allows you to place the unit in the smallest of spaces, while the full-metal body provides excellent rigidity and minimises the adverse effects of vibration on final sound quality.
When listening to Hi-Res music via the UD-301-X’s dual-monaural headphone amplifier circuit, the CCLC (Coupling Capacitor-Less Circuit) delivers a rich bass sound and quick transient responses. Conventional headphone amplifier circuits cannot avoid reduction of low frequencies and misalignment of phase caused by high-pass filtering within capacitors as they couple output stages.
As digital audio data travels from a computer to the UD-301-X via a USB cable, timing control for sending/receiving data packets is defined by the UD-301-X’s internal clock which is much more accurate than that of most computers. This asynchronous transfer mode theoretically eliminates signal compromising jitter, and allows digital audio signals to travel in electrically ‘cleaner’ conditions.
