Review on 🔌 Douk Audio USB Converter XMOS XU208 Digital Interface Optical Coaxial DOP SPDIF Adapter DSD64 PCM192Khz by Christopher Sullivan

Used to convert Android USB audio to digital SPDIF for forwarding to minidsp CDSP8x12 in car audio system. Tidal MQA streaming will play from Android (and iOS I think) with no other drivers, jailbreak, or weird USB settings. This unit can be powered by your Android device, although I modified the USB-A to Micro USB cable to be powered by a 12 volt to 5 volt converter can. Only some basic soldering skills are required to redirect the power supply (red) from your Android device to an alternative 5V power supply and connect it to ground (black) while still leaving the two USB signal wires (green and white) unaffected from android device to douk converter. It can only help to extend the battery life and capacity of your Android device. This setting sends a clean, unaltered digital signal to the minidsp. There is a definite improvement in clarity and dynamics over the line level inputs and a slightly noticeable improvement over the Bluetooth connection I use with the minidsp's Toslink input. It also allows you to test SPDIF minidsp digital input with REW and a Windows laptop. Very impressed with the new options this unit brings to my setup. 192kHz FLAC files are supported by almost any regular Android for the best CD output. Great design, metal body, Tiffany style RCA connectors for SPDIF output, compact size. I didn't need any drivers to use it with Android OTG, although the driver instructions are a bit confusing. The drivers come on a "patchy looking" CD-R that looks like it was borrowed from your uncle's cousin, who also has every season of every show ever recorded from 1971 to 2008. He only stopped recording because he thinks the government is watching him and is just as focused on ending his rule as the copyright violator for old MASH episodes while they fight global terrorism. But we still love him, after all he's family and nobody makes apple pie moonshine like him.
