NuForce uDAC-2TM

| MSRP $129 $99


Headphone Amplifier and USB DAC

Advanced NuForce technology delivers highest-resolution audio for superior sound.

If you own a laptop and love music, you need a NuForce uDAC-2. If you're a gamer, uDAC-2 brings realistic sound effects that put you in the game.

The NuForce uDAC-2 is a high-performance, 24bit/96kHz USB Digital Audio Converter (DAC) that connects your personal computer's audio to your home stereo, desktop sound system, or headphones to deliver superior sound. It improves upon our original uDAC model by providing a highly linear TOCOS volume control for improved channel tracking at low listening levels, a 24bit/96kHz USB DAC, and an improved headphone amp.

Nuforce USB Audio devices are designed to work with x86 architecture.  Tablet devices running Windows 8 (RT) are not supported.



Powerful sound in a small, affordable package.

Don't let its diminutive size fool you: the uDAC family packs a proverbial punch when it comes to improving the sound you get from your computer, meeting or exceeding the performance of audiophile-grade CD players. uDAC is also flexible: its outputs include analog RCA, digital coaxial, and high-performance headphone outputs to accommodate most computers and self-powering headphones.


Why the little uDAC can make such a big difference.

The DAC (Digital Audio Converter) in most laptops are typically not designed to deliver best-quality sound. This can result in subtle errors in the rebuilding process, diminishing audio quality. Advanced NuForce DACs create a warmer, more detailed approximation of the source file. Audio sounds richer and fuller, with more clarity on the high and and more depth and power in the mids and lows. You'll hear details in your favorite music you never heard before. Your favorite headphones and speakers reproduce sound to their full potential.

  • High voltage 2V analog output
  • A highly linear TOCOS volume control for improved channel tracking at low listening levels
  • No capacitors in any of the audio signal paths
  • USB-powered, no external power supply required
  • Headphones impedance between 16 ohm to 300 ohm are suitable for use with Icon uDAC-2

Analog channel imbalance note

Notes For Recording Engineer: The uDAC-2 is designed for consumer playback of digital music and has not been calibrated for professional recording. At the 9 o'clock volume indicator, there is hardly any signal; further, analog pots do not behave reliably. At normal listening levels, the volume tracking is within 1dB. The uDAC-2 volume maxes out at around 0dB input (maximum digital input). THD+N around 1% is intentional to target the voltage rail limit in order to achieve the loudest possible, but distortionless, music playback. Short of 1% THD at 0dB input, the DAC2 is not at its voltage limit, which results in diminished volume for music.

"...The beauty of the uDAC-2 is its blend of clarity and instrumental separation. Each instrument sounds clear, yet not in a forced, painful, or artificial way. Instead, the uDAC-2’s clarity is the real deal, especially when you stop to think about how live music actually sounds.
