Dutch & Dutch 8c with multiple sources


I’m really interested in getting the Dutch & Dutch 8c. I want to use a Mac mini for music, however I also want to be able to run the audio from my TV through the them. How would I do this?

Is your connection from the TV , Toslink, SPDIF , HDMI or analog ?  You could email Dutch and Dutch  explain what you're trying to do. They were always considerate and helpful. 
If I use a cheap external dac as a preamp then I’m limiting the quality of the input to the 8c, which is fine for tv but is terrible for music from the computer
