Hi first post here. I have one of the new iMacs and would like to be able to play the wave and flac files I have on it on my Cambridge CXA60 amp without a drop in quality. I find the BT100 dongle a waste of time so want to connect via Toslink cable. I started by trying to run anOptical Mini TOSLINK Cable from the headphone jack to one of my Amps digital inputs. Despite checking all the connections etc I couldn’t get the Amp to play any music. I’ve since learned that the headphone jack is no longer an optical out which I guess explains a lot! Is there another way of streaming Hi Res music (Wav, Flac etc.) from my Mac to Amp? Hope someone can help.
