Rdc2000, when you indicate you converted your AAC files to ALAC, did you rerip your CDs? Or did you literally convert the AACs to ALAC? If you did the latter, you don't have lossless, you have blowup lossy files in a lossless format.
Hopefully, when you indicated convert you meant convert your entire library a la reripping to the lossless format.
