Back in 2010 I bought a Mac Mini and started ripping my cds to AIFFs. It didn't take too long to stop playing cds and make the switch to using the Mac as my main source. A couple year ago I removed the hard drive from an ipod classic, installed sd cards with 512gb and 256gb of memory, and loaded the music library on the ipod.
My ipod is connected to a Nuforce icon ido which takes the digital signal which is fed to my dac. I sit with the ipod next to me and have easy access to all of my cds. It sounds identical to the Mac mini, saves wear on the computer, and couldn't be easier to use.
I know the ipods are pretty much obsolete, but I love the mine works. If the library on the Mac gets much larger, I'll swap in another 512gb card for the 256gb.
