It is unfortunately not possible to play SACD, MP3 or WMA on the CXC. The CXC uses the same S3 servo as our Azur CD players. It is optimised for CD playback only. To play back MP3/WMA discs, The Topaz CD10 or CXUHD can be used. For total universal playback including SACD discs, the CXUHD will be able play all of these formats.
