Matchstikman you really need to try and demo a SACD player in your own system.
As regards the software SACD has a large slant towards Jazz and Classical-there are a few new rock/pop/alternative releases but not many.
Of course there are quite a few rereleases-the most notiable being the Stones,Dylan and The Police.
The double edge sword with SACD hybrid releases is that the Redbook layer is remastered too,I have found at my level (check my system)the Redbook layer is enough for me because my more expensive CD player is my best playback machine and these discs sound (mostly)great but also on my SACD player(a mere $750 list in it's day) the difference between layers is not noticeable to any great extent.
It's long been my contention that SACD will survive probably only as an audiophille format and I think the releases so far pretty much reflect that.
Sales are up on SACD but I do think this is due to the big name hybrid releases such as Floyd,The Stones,Dylan and The Police-all of which sound great on Redbook and the vast majority were probably bought for this.
Try for yourself.
Oh and I won't bother trying to get some manners out of some people on these discussions,they seem incapable of it.
