Heard the 7's at RMAF this year in a very small room - surely too small for a speaker this size. They were powered by all ARC electronics. There were maybe six chairs in the cramped space and attendees were fighting over them because the sound was amazing. Crystalline clear, precise, nothing overdone or out of place. The sense of desire in the room was palpable. Heard the 9's last year in one of the large salons and they were equally incredible.
