Streaming computer app/utility application for Sprout

I picked up a Sprout and love it so far for my small home hi-fi to older Epos ES12 speakers.
I had been streaming my music to a Google Chrome Audiocast puck, but I was using an app called AirParrot 2 to send the music to the puck. It can stream basically anything from your computer: files, screen, audio programs like iTunes.
I am aware of services like ROON, and others, but I was wondering if there was a smarter or “best” audiophile way to stream to the Sprout from my own computer library via an app or utility?

Thank you very much.
