This one was unexpected. At a Stereophile show in Manhattan in 2005(?), Roman Audio Centurions powered by Krell gear. We put on a Brad Mehldau JVC XRCD, a sampler, "In the Wee Small Hours of the Night". About a dozen people in the room, and nobody said a word, or even breathed very loudly, through the entire 6+ minute cut. Even when it ended, people were just still gobsmacked and silent for another 10 seconds. Too bad the poor guy couldn't get the brand off the ground.
