OK, I posted a thread here a week ago saying I was going to get the new Alison Krauss SACD ordered from Towerrecords.com and I got it tonight. Very weird thing happened. I noticed it is released on the Rounder record label and is a hybrid disk (can be played on both SACD and Redbook players). I played the entire disk before realizing it was a hybrid recording. Seeing as I don't have the Redbook version, I at first thought I would have nothing to compare it to. I did realize that I had the volume pretty cranked (at about the 10:00 position on my receiver)for a rather tame volume level overall. I thought it was a pretty clean recording however and Alison's voice sounded wonderful as always. However, it was then I noticed it was a hybrid disk and had a Redbook layer. I of course got curious and switched over to Redbook format. What I heard confused/surprised me. The Redbook layer was noticably louder at the same level volume on the receiver. Also, for the first time in my SACD lifetime I was hard pressed to hear the usual difference I hear in SACD...which is usually a LOT. The Redbook layer sounded spectacular and that added output level did not transport a lot of noice to the recording. It was also very clean and sonically satisfying. Anybody have any hybrid disks out there that have experienced this phenomenon? I'm actually debating which layer I'm preferring right now and this is a first for me. My system is not the kind that would disguise the differences either. I have Paradigm Reference speakers. Please help. I'm going to spend the next few days with this disk and critically listen more carefully, but these are my initial impressions after a couple hours. Thanks for your input.
