20 reissues announced in the new high-fidelity SHM-SACD single-layer format which are fully compatible with standard SACD players, but do not play on standard CD players.
SHM-SACD (Super High Material SACD) is the ultimate Super Audio CD that utilizes the materials and technologies that were developed for the SHM-CD to further enhance the audio-resolution. What works wonders for a low resolution format such as CD should offer even greater sonic improvements in a real high resolution format such as SACD.
Some of these have appeared on SACD before, others never have. The latter are new 2010 DSD remasters from the analog tapes; for the others existing SACD masters have been reused.
