Joel,

You stripped your whole CD collection to a Hard drive and then will output PCM into a 518 straight from your PC? Let me know how it sounds! I'm building a new theater room and plan to have a PC hooked up to my system. I to have a 518 and use a 568.2mm. The 518 should clean up the sound from your PC quite nicely!
