those idiots of the audio industry want you to buy the SACD at premium price, and at the same time make sure that you will have the hardest of time putting the music on whatever device you want. those guys must all be over 90 to imagine this is a legit business and the only way we will want to listen to music is by pushing the SACD into the toaster @home.
you buy a mp3 on amazon or whatever, you copy it wherever you like. and if you lose it all, just download it again for free! it's cheap works everywhere and doesn't sound bad.
now buy a SACD for a lot more money, after a few years you won't be able to read some of them because it's been like that since the first CD. at which point the music industry advises you to go F yourself an buy a new copy.
the actual resolution is still about the same as highres PCM(because the high frequency noises must be filtered out) and was usually done from highres PCM anyway, but hush don't tell anybody.
and with all this, the SACD never took off in the sales? wow now that's a surprise.
don't buy SACD, don't buy anything with some crap DRM system, else they will never stop doing it?
