Alright then! I blew the dust off an old laptop, downloaded foobar again and ripped a bunch of cd's to WAV files (plenty of space, hardly any memory used at all). I hooked the lappy up to my receiver via HDMI and can control everything from my tablet or phone with the app.
I'm tickled pink. Everything worked, went smooth and I didn't break anything! Thanks for the tips here guys, and especially thanks to Buck for enduring a 3 page private conversation while he explained everything to me in detail. I'm up and running, everything is working and sounds great. Woot!
*Edit: I'm in a cd ripping frenzy right now. lol
