I think it's not catching on because people don't get it. It's not an improvment they can hear on their current boombox or shelf system type equipment, and there's nothing cheap and/or portable available for it. Think about it-CDs took off when the portable stuff got cheap enough for people to buy. Plus their competitor was tape--pretty obvious difference there. Same with DVD. To get into SACD/DVD-A is a pretty big investment for someone who just wants to listen to music (ie, someone not like us). Hell, it's a pretty big investment if you already have 2 disc players and WAF, like me!
