I have embraced the SACD format and am using a Marantz SA12-S1. I do think it sounds better than redbook, and I am pleased at the new titles that are coming out. Elusive Disc has 20 something pages of SACDs and it is increasing all the time. Many are classical but there is also Dire Straits and Roy Orbison and and Elton John and Patricia Barber and lots of jazz. My local Best Buy has decreased their SACD offerings (only local place to buy). I don't worry about the format's longevity. I will just buy all I can and enjoy long term. My 2-channel listening is not mainstream anyway. I also have cds but no LPs.
