Buy the server and use Pure Music. Anything using MP3 is crap. If you already have a Mac just try it with Pure Music. You can use it for 15 days at no cost. If the Berkeley has a USB port go straight from the computer to it. Most USB to SP DIF are poor. If the Dac has only SP DIF inputs, use the toslink out of the Mac into it.
Use Memory play and HOG with Pure Music. If you don't know how, I will tell you.
