The ATC room demonstrating SCM100ASLT speakers, for me, probably the best sound of the show value for money considered. Of course if money is no object, the MBL, Avantgarde and Krell demonstrations were about as good as things get IMHO. I was also impressed with the B&W 801D4 demonstration, strange choice of music, but, the speakers sounded wonderful and the guy giving the demonstration/talk was very interesting and informative.
I was so blown away by the ATC demonstration, I am thinking about replacing my Magico A5 speakers and McIntosh MC312 power amp, with a pair of stand mount SCM100ASL speakers in piano gloss black.
