Just be sure that when listening to multichannel SACDs or DVD-As (or when calibrating the 950) you need to be in multichannel mode first or else you will be stuck in stereo mode. It was very disconcerting when listening to James Taylor's Hourglass after a stereo CD, only to have his voice muted and sounding like he was singing from the bottom of a deep well. You can get into multichannel mode by switching to a dolby digital mode; there may be other ways as well. Just search this forum for other SACD and calibration topics.
BTW, Norah Jones is due immently for an SACD release, and Steve Hoffman indicates that he is working on an SACD of the late, great Eva Cassidy's 'Songbird'. In the meantime, in addition to the Stones SACDs, I highly recommend all of Alison Krauss' SACD offerings (I found the best prices at the http://www.rounder.com web site). Alison's latest release, Live, is supposed to be out as an SACD (the red book is out already) probably around the same time as the concert DVD. As for DVD-A, Appalachian Journey with Yo-Yo Ma, Edgar Meyer and Mark O'Connor is superb, but it is just 2 channel. If you're into eclectic stuff, Bela Fleck has an interesting, Grammy nominated SACD, Tabula Rasa, that I really like, but may be an acquired taste. I only hope that Uncommon Ritual is released in SACD some day.
