I guess that I'm a little out of the loop on the issue here, but can I ask a question? Why are you trying to avoid the computer? Most of them have mighty good audio circuits [many of those are excellent]. For example, I have my MAC hooked up to my receiver with a 3.5mm plug at the MAC, a ground loop isolator to cut out the buzz that is common with such hookups, and left and right RCA plug at the receiver. To cut to the chase, everything works and sounds great. Streaming devices are great if you want wireless music through the whole house. But short of that, why not just do things the easy way?
