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?

I sold the D&D 8c but I always used all digital AES3 to the speakers but for what you want you'll need a preamp or DAC with multiple inputs.  
I don’t want to introduce another dac into the system. Can someone please tell me the names of a few preamps that would work?
