Ok, so let's say I get the A3 w/ DAC card. Now help me out here. I have two sources for audio, my Macbook and my Android phone (I use the phone for Tidal, which is blocked on my work-issue PC, and I also keep flac files on the phone and play them via Foobar). I'd like not to have to keep plugging and unplugging...
I see that the USB input is that old school big square thing like what I plug into my printer. What would happen if I connected the A3 to a USB hub, and then connected both the phone and the Mac to the hub? Either a hub dedicated for this purpose, or the USB hub I already have and use to connect the printer? Or am I stuck with having that one USB line to the A3 and switching it manually from the Mac to the phone?
