Inside the DAC3 is a high-performance headphone amplifier that takes your headphones and takes the highs even higher and the lows even lower.
Plus, the DAC3 features a variable line-level output that gives you greater control, flexibility, and improved sound quality. Which means you can use it with a wide range of equipment to optimize your listening experience.
Small? Yes. Powerful? Definitely. The DAC3’s playback performance gives you detail and clarity your headphones usually can’t provide. It’s like the difference between reading a description of a concert and actually being there.
You won’t need batteries or charging. You also won’t need additional software or drivers. The DAC3 draws what little power it needs through a double regulated USB-C connection. Just plug the included cables into your phone, tablet or computer and let the DAC3 show you everything you’ve been missing from your music.

Setup guide
DAC3 Internal Converter
The heart of the DAC3 is the ES9281A PRO DAC, which is well-regarded for its low noise and high fidelity. Due to the high signal-to-noise specs of the ES9281A PRO and the added benefit of double redundancy power source conversion and filtering, the DAC3 presents impressive low noise and low distortion characteristics. The DAC3 can process digital audio at any bit depth up to 32 bits and any sample rate up to 192kHz. DAC3 pads (upsampled) all bit depths internally to 32-bits, thus achieving a higher signal-to-noise ratio.
DAC3 Headphone Amplifier
The DAC3 contains a high-performance headphone amplifier based on the LME49726 low-noise opamp. This amp is able to provide low-impedance, high-fidelity audio and a 2-volt output which easily drives a wide range of headphones, satisfying even the most demanding headphone enthusiasts. The DAC3’s relay-controlled stereo output can also be connected to any system with an analog audio input, such as Audioengine powered speakers.
DAC3 Power
The DAC3 is powered directly from the USB bus and power is passed through two stages of regulation to ensure no USB bus power variations affect the audio quality. This low-noise, low-ripple power supply is located on a separate circuit board for extra isolation and thermal management.
DAC3 Volume Control
Volume for headphones and line-out is controlled directly from the DAC3 side panel. Smoothly adjust volume levels at fine increments without any undesirable noise or channel imbalance at lower volumes.
