Hmm.. the reason for ripping all my CDs at 192 in the first place was so that I'd be able to reconvert into a new format at a later time without introducing too many new artifacts. My understanding was that 192 is pretty close to the original source... of course who knows if there are particular artifact problems from MP3->WMA in general because of the different coding schemes used.

I'd agree with you if they were at 128, but does anyone have any knowledge of what would actually happen (i.e. how bad 192 MP3->WMA is vs. WAV->WMA at the same ending bitrate)?
