With regard to mobile DAC (i.e. DAC connecting to smartphones) perhaps not too much more power, as most smartphone would likely not be setup to provide more than a small amount (i know the N6P can only provide minimal power over the Usb-c as a host).
However, I am very much looking forward to the whole "multi-use cable ends" thing. I mean, I can use the same cable to: Charge my phone, connect my DAC to my phone, connect my phone to my PC, connect my PC to my DAC, this is so awesome. I use my DAC a lot with my android phone, and the whole 'OTG' thing is very often a problem, lot of cables don't work, or only work half the time etc.
I do have a question though: are there any usb-c DACs out there yet? Any in the works that people know of?
ETA: I just talked to a google store guy (not sure about how true this is, sounds true enough but I cannot find a reliable source that authenticates this), but 5x and 6p are capable of upto 9W-ish of power (the guy told me like 1.9 odd Amps). So that's good news, hopefully Fiio will make a new versino of their E18 that can draw more power/charge faster and use usb-c to usb-c (if nothing else, MERELY for the simplicity it will create in my life...i can finally have only 1 type of cable and no little OTA cable that gets lost all the time).
