I have to agree with Gonk, I re-ripped most of my CD's over the last few months using Winamp, High Quality settings at 256kps Bit rate. I'm streaming the Audio from my PC, through my XBox 360 to the 990. This allows me to scroll through 7,000 plus MP3's so It's a great feature but I can tell the difference between the CD and the MP3's. For serious musice sessions I go to the CD, background or party music I stream through the XBox. I have been thinking about re-ripping everything at 320kbps, anyone tried that ?
