I have about 20 of each. There is not a single SACD that sounds better than my worse sounding DVD-A. DVD-A buries the SACD format. At least to my ears...

Maybe you have not listened to the DSOTM SACD.
I find the two formats indistinguishable and would attribute the apparent superiority of any disc to the strength of its mastering, or mixing in the case of surround tracks.
