But in this case all you are really testing is the mastering of the SACD version of FCA. That is not a good way to "test" the viability of the SACD technology as a whole. I would think a better way, is to find a well recorded an mastered SACD and compare it to the original. Plus "live" records are notoriuosly poorly recorded as compared to studio records. There is no way to control the acoustic environment in an arena or concert hall, as well as you can in a recording studio.
I think the original recording quality, and the expertise that was employed in the mastering process is far more important that the technology that was used to encode the disc, CD, SACD, DVD-A.
