Hey guys. Any help here would be much appreciated!! I have just acquired a bunch of m4a music files in 251 bitrate, which I want to add to my collection of mp3 music files which are in 320 bitrate. I need to convert the m4a files to mp3, however I do not want to lose quality, as I need them to be as high quality as possible for DJing. If I convert these though iTunes ("right click - create mp3 version") will I lose any quality when I convert m4a to mp3? Thanks in advance!
