D&M Holding is the name of the company that owns Marantz, McIntosh, Boston Acoustics, and several other audio/video brands; they had a mini-exhibit of their own at the Mandalay Bay. There were some formal home-theater demos, but I didn't have time to sit through those. However, I did get a good look at the new SM-11S1 Reference Power Amplifier (110Wpc, $3999), SC-11S preamplifier ($2999), and SA-11S1 two-channel SACD/CD player ($3499) from Marantz. Gorgeous stuff. Michael Fremer has these for review.
