I'm not sure what your source is but I've heard no such information regarding DSD (which yes, is used by SACD). What I have heard, with my own ears, is a significant improvement in recorded sound quality over PCM (particularly the 44.1 & 48Khz sampling rates). If you read the technical specs of DSD you will see that it is in fact the closest digital equivalent of an analog waveform possible, plain & simple. Indeed if you begin to look for flaws in the technical specs you will find countless ones in that of PCM - Sony & Philips knew this which is why they created DSD. At it's core DSD offers a vastly improved sampling rate (2800Khz), dynamic range (120db) & frequency response (~100Khz) - in English this means more realistic sound. As for SACD itself, it was never going to be a mainstream format, but merely a niche format for those who appreciate good sound. Enough said. As for recording let me put it this way. If I'm recording something that's only going to be heard once for all of time & will go down famously in history (say like say Queen Elizabeth II announcing that England has declared war on Australia, or perhaps U2 turning up at my local pub to play an acoustic set of their Joshua Tree album) I'd make damn sure it was recorded DSD. :-)
