Paul McGowan from PS audio posted a recommendation (video) which consists of a Mac Mini as a server. I tried it and it sounds better than all the streamers I have used in the past. To save money, I bought a used Mac mini and upgraded the HD. Also, the best DAC for USB input is the Musical Fidelity V90 ($299). The USB input outperformed the other DACs I experimented with.
Best of luck..
