I dunno. You can't argue with what people say they heard. But the San Fran Area dudes seem very into peripherals. The impedance profile of the SS10 is about as benign as it gets, and I can't imagine that biamping would make any difference. And the highs have a 3-way switch, with the first setting being elevated about 2 dB. So I'm pretty sure there were no rolled off highs. Just a personal opinion.
