USB compatability
Are  you using a basic phone to USB cable?  That won't work.  You need an OTG cable, on the go cable.  It looks like a normal micro to usb but it's not.  Amazingly cheap fix.

Which in-wall speaker wire

Listening room setup + library
Great pictures.  Books do wonders for absorbing sound.  You can probably even put those speakers closer to the walls if they are packed with books.  Just be careful which speakers you pick.  Some like small rooms better than others.  Bookshelf spe... 
What’s the best DAC match for the Cambridge Audio CXC original or V2?
I think the Cambridge is better than the Oppo.  Definitely warmer/smoother.
