Alright so a lot of the cd players use Legato link conversion to reproduce the rolloff of sound from 20khz and up. That way the cd instead of getting cutoff at 20 khz continues it's rolloff to say between 30 or 40 khz. Now a lot of people are listening to SACD in 2 channel. Is there a significant improvement in this case of redbook vs SACD? Is there any info I'm missin here? I guess my point is: Is SACD or DVDAudio really a big stepup? I've heard the CC demoes w/ crappy sony speakers and was only semi-impressed?
