What a stupid question. Yes, DVD-Audio has had it, but there are over 4000 SACD releases worldwide and more coming every day from European labels! Does that sound DOOMED??
Why in God's name do so many uninformed audiophiles talk about the failure of SACD??
AUDIOPHILE AUDITION reviews more of them than anyone: www.audaud.com
***Couldn't find your current Poll on What Audio Format for Hi-Def DVDs (newsletter link didn't work), but that's easy = Uncompressed 5.1 PCM - there's plenty of room - no need for Dolby or DTS anymore!
