Greatly improved sound quality of an old DAC

I originally bought this item for connecting the new USB-C iPhone to the DAC. I found it still drains battery after long time use so I gave up. However I noticed that I never heard sound this good, with a new multibit DAC with a poor CMedia USB interface. I had a new idea, to use this module for a 20yr old PCM1793 DAC and the result is fantastic - sound is much better and also adds a usb2 instead of usb1 interface.
