Hey man, I don't care if DSD goes mainstream or not. The majority of mainstream music would benefit very little from the higher sampling rate. Most of the Rhino CD remasters sound great...
I think that where DSD will matter for decades to come is in remasters of the older jazz, blues, bluegrass, and classical 30 ips master analog reels of historically significant recordings.
Case-in-Point:
I'll never be willing to spend the cash for a MINT original pressing of Ellington's "Blues in Orbit," but damn the DSD MoFi I bought for small coin sounds F'ing incredible...
