The OP has many choices at many price points, that is always a good thing. One person mentioned using a Mac mini as a simple solution. I am not knocking any audio setup, but I think it ironic because I moved away from a computer (multi-functional device) because I wanted a device designed, engineered and built as a music server for audio. All the music servers mentioned have great audio, so it may just be your price point. Again I picked Bluesound for the good engineering and customer service at a good price. It fits my needs, I am not one to spend thousands of dollars on a music server. If I wanted to upgrade the DAC, I can do so by adding a much better one like the Ayre Codex.
