@audioman58 , gowanus mentioned getting the Eversolo which is all the rage right now. Comes in 2 flavors: $700/1300 which I believe is a great deal for what you get. You can plug in your USB drive until you are able to get a drive that installs directly inside the streamer. With this type of unit, you don't even need a network to play your tunes. DAC/ Preamp/Streamer all in one. Your current drive may be able to install inside the streamer.
Enjoy the Music
