DSD, PCM: what's going on?

摘要

A few years ago I read a comment in HFN about the fact that some record companies do not use DSD for SACD - the proprietary system developed by Sony/ Philips to give much greater resolution to recordings compared with CD, along with multichannel capability.Some of the companies then incorrectly put the DSD logo on both the jewel case and the disc, which is confusing and misleading.I have noticed recently that some labels, who once properly recorded their SACDs in DSD, are now using 24-bit/96kHz PCM. For example, one classical label now appears to be using PCM, stating 'Recorded in 24-bit/96kHz' on jewel cases, but continues to use the DSD logo on cases and discs. Is this because the SACD/DSD system is thought to be obsolete and recording companies are consolidating their operations?
