Lossless conversion format help


I need to convert either FLAC or AIFF files to WMA lossless. Can anyone recommend a program that will maintain the highest level of lossless conversion and sound quality while maintaining artist/song tags? Also would either FLAC or AIFF be appreciably better to start with?

mmm im sorry I do not, but I do know a good program that converts to Flacs and AIFF to Apple Lossless if that another option. Its called XLD. Just google that and you will find it, it is just freeware. Good Luck!!
