Volume is controlled directly from the D1 front panel via the digitally-controlled analog potentiometer. 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. The high-performance headphone output was designed for a wide range of headphones and will satisfy even the most demanding headphone enthusiasts. The D1 includes a headphone amp based on the TI OPA2134 low noise opamp. The D1 can process digital audio at any bit depth up to 24-bits and any sample rate up to 192kHz. Volume is controlled via the computer, an LME49726 opamp boosts the output signal allowing for usage with headphones from 12 Ohms to 10k Ohms. Files can be played natively up to 24/96, downsampling is used for 192 files. 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 D3 uses the AKM4396 DAC chip, the same one in Audioengine’s D1 DAC/headphone amplifier. The D1 uses the AK4396 DAC, which is well-regarded for its low noise and high fidelity. B1 uses Bluetooth 4.0 chip, stable transmission and low power consumption, effective transmission range up to 30 M. The use of plug-and-play is very convenient.
