You took the easiest example possible. How about setting up a a laptop as a music server, installing Jriver, Foobar, etc,, and then installing an outboard DAC and have your software ready to play pretty much any digital file up to DSD. Also, factor in setting up the software on both your computer and an iPhone, iPad, etc, so they can act as a remote to control the server. Tell me how easy that is.
its pretty much as easy as you describe. most folks who can install a free player like Foobar can handle Jriver or whatever software they want to use. in addition to the installation, there are going to be lots of settings one will want to enable and disable in the software. its time consuming and sometimes irritating, but its pretty easy if a person has the patience.
i dont, so for an even easier method i went with an out-of-the-box solution with the Vortexbox Appliance.
