The problem: I hate cables and the thought of plugging back and forth my smartphone from its charger to the USB OTG cable connected to a DAC is off-putting. My ideal setup would include smartphone --> (wireless) --> wifi device (instead of USB OTG) --> usb DAC. Question: are there any wifi devices that can transport data from a smartphone to a usb DAC in a pass-through manner without decoding the files? Like this one on Indigogo that failed to get support. I know that that there are small wifi DACs like the Chromecast Audio that can stream from your smartphone, but from what I understand it cannot purely transport audio to external DAC, and it supports only 24/96khz.
