Not sure about $2000 for a dedicated music playing computer.
I have a pi3 ($40) that I hooked up to my existing sound system (second hand NAD amp ($90), second hand speakers ($0), DAC ($300, I splurged on this one)) which runs mpc and have a chromecast ($30) for streaming. I know the latter isn’t really dedicated but I can control both from any device (computer, phone, tablet) and have the option of local files or streaming from a service…for less than $100.
