I've been ripping RBCD using MS Media Player using a bitrate of 320, and then burn it back to a CD, to make a replica/copy. What I find interesting is, I can't seem to be able to notice ANY difference with the original source. From slam, micro dynamic, instrument details, etc, no difference. So, in my opinion, the bitrate at 320 seems to be the optimal bitrate.
Thoughts, opinions, and experiences?
