DVD-A? You bet. I've really only got a couple of SACDs, but quite a few DVD-As. Even with my modest gear I find a huge difference vs standard CDs. Of course there differences in the master of the recordings, distinct 5.1 vs. virtual-style 5.1 like PLII, Neo, circle-surround, etc., but the big difference between the DVD-A and SACD formats I enjoy are the potential for video content in addition to the hi-res audio.
That, and the fact that I can loan DVD-As to friends who only have DTS decoding available (which sound pretty good in and of itself - not quite MLP lossless but still - arguably - better than CD ) and get them hooked on surround mastered music too.
