Cambridge Audio CXC Frequently Asked Questions How can I play SACD or MP3/WMA discs on the CXC? It is not possible to play SACD, MP3 or WMA discs on the CXC. The CXC uses the same S3 servo as our Azur CD players and is optimised for CD playback only. To playback MP3/WMA discs, The Topaz CD10 or CXUHD can be used. For total universal playback including SACD discs, we would recommend the CXUHD.
