Ayre's Mini MX-R Monos
They're so small, you'd almost have to bet they're class-D, but the $16,500/pair 300W MX-Rs are linear all the way. The tiny brutes were fed by Ayre's C-5xe universal player ($5950) and K-1x preamplifier ($8600 with phono section), and Ayre cables. The system, which included Vandersteen Quatro Wood speakers, sounded far more detailed and lithe than the MX-Rs did at CES. MAybe it's the smaller room, or maybe it's those Quatros. Heck, it could even be that Ayre's Charlie Hansen can't leave a good thing alone either.
I seriously considered camping out in the Ayre/Vandersteen Room for the duration of the show.
