Yes, I have it.  It is a stereo-only SACD.  It is also not a hybrid (i.e. no CD layer).  I haven't listened to it in years, but I remember it sounding very good.   It is an excellent performance, except for Ozawa's sprint through the March of the Souls section.  
I really like the M9!  I'm not sure if I'd pay the premium to get it again on SACD though.  I haven't listened to the M9 in a few years either, but remember my only real disppointment being a lack of power from some of the brass.  I LOVE Ozawa's way with M9 though, including the commercial BSO one and the radio-rip of his final BSO concert.  I am considering the Japanese DVD or Blu-Ray release of that final BSO concert, but it is probably a little pricey for my blood.  I'm spending too much money on tennis these days to spend $70+ on a Blu-Ray disc.
