I am the original owner of this excellent sounding DAC / headphone amp.
Selling as my new Peachtree amp has a built in headphone amp & DAC.
All of the original accessories and packaging will be included.I will ship anywhere in the USA for $13 using USPS Priority Mail. Will also ship to Canada.
I will cover Paypal fees.

Operating Temperature: 32 to 95 degrees F Non-operating Temp: -4 to 113 degrees F Relative Humidity: 5% to 95% non-condensing D1 Internal Converter The D1 uses the AK4396 DAC, which is well-regarded for its low noise and high fidelity. Due to the high signal-to-noise specs of the AK4396 and the added benefit of double redundancy power source conversion and filtering, the D1 presents impressive low noise and low distortion characteristics. The D1 can process digital audio at any bit depth up to 24-bits and any sample rate up to 192kHz. D1 Headphone Amplifier
The D1 includes a headphone amp based on the TI OPA2134 low noise opamp. The high-performance headphone output was designed for a wide range of headphones and will satisfy even the most demanding headphone enthusiasts. D1 Power
The D1 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. D1 Volume Control
Volume is controlled directly from the D1 front panel via the digitally-controlled analog potentiometer.
