I also heard the speakers in NYC. I felt them to be quite special in the midrange and treble. Remarkable, in fact. However, when the notes would drift into the low frequencies, I felt the sound became quite congested and wooly. It needs to be pointed out that the three times I heard them over the two days, the music was always piano based, and it is difficult to judge any component on such a limited scope of music.
And, Russ, I have always heard that the Bosendorfer is a he man's piano.
