Audioengine D3 24-bit USB DAC/Headphone Amp


  • $ 9900

Audioengine D3 Premium 24-bit USB DAC

The Audioengine D3 Premium 24-bit DAC allows you to bypass your computer's headphone output and send music directly through a USB port for noticeably improved fidelity and a higher output.

The D3 is a powerful yet portable converter with performance and features usually found in more expensive DACs and is the perfect interface between your computer and headphones or any music system.

"Audioengine has hit its mark with the D3. A good price, great delivery and well-kempt sound quality round out the tiny package for the computer desktop junkie and budget audiophile alike. Its DAC is highly resolving for a compact component and the headphone amplifier should fit the bill for a very wide range of headphone usage, should you choose to go that route."
– Brian Hunter, Computer Audiophile

Easy setup

Setup is easy and no special software is needed, making D3 a true plug-and-play solution. The D3 plugs directly into a USB port on your computer so no external power supply or cables are needed. The output of the D3 connects to headphones, powered speakers, or any audio system. The D3 also has a sample rate indicator that shows sample rates above 48K so you'll know you're getting the most out of your HD music.


The quality of most computer headphone outputs isn't generally very inspiring, so the D3 provides a better option by streaming audio from your computer's USB port and directly connecting to your music system or headphones. The D3 DAC is the perfect way to get great-sounding music not only from your computer to headphones but also from your computer to any music system.

Designed for the headphone enthusiast

D3 will process digital audio at any bit depth up to 24 bits and any native sample rate to 96KHz. With its high signal-to-noise ratio and low distortion, the D3 delivers sound quality generally heard only in more expensive DACs. The high-performance headphone amplifier was designed for a wide range of headphones and will satisfy even the most demanding headphone enthusiast with its high output and revealing sound. The D3's asynchronous data transfer carefully controls USB streaming audio from any computer which greatly improves audio performance.
