Making SACD's is not as trivial as it sounds. There still is a limited amount of pro gear out there that works in DSD, and the bulk of it works with a maximum of 8 channels. DSD digital editors are also a rare breed. Not to mention that there is only one Hybrid manufacturing plant in the world (at this point, a new 2nd plant in Hollywood is scheduled to begin manufacturing in mid to late September). That's a hellova bottleneck.
Are you going to buy the Rolling Stones SACDs?
I've preordered a few already. I suspect that the recordings, despite remastering, will be far less than what SACD is capable of reproducing. But it is exciting to see a large block of music from major artists come out in the new format, and that's why I'm buying. What do you think the major labels (especially Sony, that controls vast numbers of recordings AND manufactures SACD equipment) are waiting for? Seems logical to me that getting more software out would speed sales of the electronics and interest more of the general public in the new format. Releasing SACDs would also immediately protect the record companies from copyright infringement, at least until someone manufactures an SACD burner.
