Did anyone hear the Zu room at CES/THE 2011?

I did. The first time I listened, they were playing the giant $45k (Dominance?) speakers, biamplified with a pair of Pass Labs XA30.5s. I thought they sounded excellent. Then I went back, and wasn't so impressed witht he sound. I saw that they had replaced the Pass with a 2.5 Watt SET amp (I think the internal sub was still powered by a Pass). To me, the life, energy, resolution, and naturalness just wasn't there. At least one other person there who had heard both said he preferred the tube amp, saying it "made him feel more connected to the music." I wanted to say, "No, the king is naked! You're just saying that because you think you're supposed to," but I didn't. I recognize that he may have heard something I didn't. Apparently, others thought the same as him, because they left the tube amp in for the rest of the show. So my question is, was I the only one who thought the Pass sounded better?
