I used a MacBook Pro with Amarra and an off ramp 4 USB converter before I switched to a Salk Stream music server. It's a Linux based, totally stripped down computer that only plays music files. It come with an internal 2 TB hard drive to store all you files and it connects to your server. It's been a life saver for me. My old set up was glitchy and I hated having the computer on all the time to listen to music. Best of all it sounds so much better, it's rock solid stable, and I control it using a ipad, Mpad app. The streamer costs about $1200 and the app is $3.
