The first statement is true, but has a limit. SACD came along way before the latest BluRay formats and has that "audiophile magic dust" aura of DSD attached to it. It is "special" to it's devotees even requiring special players to be able to access it. But DSD as a superior sounding format is a myth as is being highlighted in this thread.
Truth is SACD as a format has a foot in the grave, and DSD-A is there already, and rightly so. Despite the audiophile magic dust aura of DSD, there is nothing special about it. For the multichannel world, BD offers about as many channels in lossless high data rate PCM as we could ever ask for. It's way past time to move to it for the production of the multich music standard format. Hanging on to SACD or DVD-A makes as much sense as hanging on to vinyl as the 2ch standard for high fidelity playback.
Look at what Mark Waldrep's AIX records is offering on one BD, 5.1 Stage mix, 5.1 Audience mix, 2 channel stereo 24/96 mix, with HD video included.
SACD and DSD-A were great formats, but progress and the SOTA has passed them by.
