I'm still new to SACD, but two that I have found that are outstanding are Norah Jones "Come Away With Me" and Willie Nelson "Stardust". There is a lot of detail to be heard in both artist's voices, and SACD seems to really let bring it out vs. redbook.
Best sounding SACD's to show-off system
I like to show-off my Wilson Audio W/P6s and Krell 350mcx to friends and try to get them to understand the rush of high-end audio, and I have to some degree, but what SACD's out there that are recorded best! Something that will really make them melt with goose-bumps. Thanks!!
