Product Research
Features
Overview: The Audioengine D1P Digital-to-Analog Converter (DAC) is a portable headphone amp and 32-bit DAC to provide a premium listening experience. It can be used with your smartphone, or with your computer to bypass its internal soundcard. It is compatible with Android and iOS devices, as well as Windows and macOS computers. It has USB-C and Optical Digital (Toslink) inputs, plus 3.5mm mini-jack and stereo RCA analog outputs. The DAC comes with a USB-C cable, a USB-C to Lightning cable, and a microfiber storage pouch. The D1P DAC is covered by a 3-year Limited Warranty.
Design: The D1P is built with premium components to provide superior performance and sound quality. It has a Savtech SA9312 USB chip, an ESS ES9219C digital-to-audio converter, and a Cirrus Logic CS8416 optical input. The D1P supports a wide variety of high-res audio formats:, including FLAC, PCM, DSD, and MQA.
MQA Renderer: The Audioengine D1P uses MQA Renderer technology to an MQA Core signal and complete the final unfold of an MQA file. MQA (Master Quality Authenticated) audio files are stored original master recordings that can be downloaded or streamed, to give you audio the way the artist intended.
LED Indicator: The front panel has an LED indicator that glows to indicate the status, format, and sampling rate (see Note below):
- White: PCM 32kHz to 48kHz
- Green: PCM 88.2kHz to 192kHz, DSD 64, Optical
- Blue: PCM 352.8kHz to 384kHz, DSD 128
- Purple: MQA Rendering
Power Requirements: The D1P is powered through the USB port (5V) and has a minimal power draw. It can be powered by your mobile device or computer. If you are using the optical input, any 5V DC USB-C power supply will suffice.
Break-in Period: The D1P will sound better over time. Although it will sound great out ot the box, Audioengine recommends you play the DAC for 40 to 50 hours before doing any critical listening. This "break-in" period will allow the internal components to reach their peak performance.

I am astonished at the sound quality from my Audioengine D1P. I primarily use it to listen to ITunes from my IPhone X. The DAC was simple to hook up to my REGA ELEX amp which plays through my REGA JURA speakers. A great purchase and equally great customer service from Crutchfield.
