Are you an audiophile? HI-FI enthusiast? The quality of most computer headphone outputs isn't generally very inspiring. I'm selling a DAC from Audioengine. This 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. Take your listening and music quality to the next level. Send high-quality music to your headphones or any audio system. 

This is a portable USB audio converter for Mac or PC, 24-bit digital to analog converter. 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. 

Highlights: 
Setup is easy and no special software is needed, making D3 a true plug-and-play solution. It just 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, Audioengine 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. This is a high performance headphone amp. Just plug and play!
