NuForce uDAC-2 is a high-performance USB Digital Audio Converter (DAC) that connects your personal computer's audio with your home stereo, desktop sound system, or headphones. The quality and versatility of the uDAC-2's performance belie its diminutive size. With its extensive power supply, filtering capabilities and charge-pump circuit as a foundation, the uDAC-2 processes incoming data via a USB audio receiver. A D/A converter chip then translates the data to a two-volt analog signal.The NuForce uDAC-2's performance equals or exceeds that of a great many audiophile CD players. The unit's exemplary flexibility -- analog RCA, digital coaxial, and high-performance headphone outputs -- is bound to satisfy the needs of the most critical music lover.

As a step beyond the successful uDAC, the uDAC-2 boasts a highly linear TOCOS volume control for improved channel tracking at low listening levels, in addition to 24bit/96kHz USB DAC and an improved headphone amp.
