A facade. A way for record companies to get rich off the same music that gullible techsuckers already own. Don't buy into the bullshit about better sound quality, especially of SACDs that were culled from digitally recorded originals and not master tapes. All CDs that are SACD are copy-protected so you can't play them on your PC, you can't rip them, and you can't upload them -- no back-ups, which is just what they want.
Austin: Hey, is that an SACD?
Me: Uh, no, I just turned my treble up.
