Comment The Truth on SACD (Score 3, Informative) 505
The recording industry is run by morons, make no mistake of that, but SACD does have quite a few technical advantages.
1) Essentially it's a brand new technology. It doesn't use PCM that everything now uses (including DVD-A). It uses a formula called DSD ( Direct Stream Digital ). It's designed to give a direct representation of the orginal analogue signal using a one bit protocol. It tries very hard to avoid the decimation artifacts that are part of the PCM process.
2)1) It has a sampling rate far in excess of standard cd's.
64* 44100 = 2.8224Mhz/s
3) SACD isn't like DVD-A in that you HAVE to have a DVD-A player to play back the audio, It is a dual layer format that has standard red book audio on one layer and the SACD audio on another layer. (It also has multi-channel capability ). To play the SACD part though you do have to have a player capable of reading the DSD info stored on the disk.
Yes, I know this sounds like a Sony Ad, it is the way that audio needs to go, as far as quality goes. CD's are really bad in comparison. If you can't hear the difference between SACD and red book, then your ears need checking.
As far the copying issue goes...If it can be listened to..it can be copied in some way.
