I realize not many people got overly excited when Sony announced that the Indigo Girls latest "All That We Let In" was being released as a surround SACD hybrid, but I like them a lot, and they are my wife's favorite act. By far. I bought this SACD yesterday but can't listen to it until I give it to my wife as a gift next week. Anybody listened to it yet? I've heard the redbook, but how's the surround mix and the sound quality on the SACD?
