A couple months ago I was in Akihabara district of Tokyo in Japan where I heard Sony's SACD, it was absolutley stunning I really felt like there was a live guitarist seven feet in front of me. It blows away stereo system I have ever heard. I might also add beleive it or not that the speakerswere sony's! The only cons I can think of is the price 3500 dollars and that it is only two channels.
