We just finished watching Hellboy at reference level (0dB on the Onk). That reference level is at an MLP of 12 feet from the M100s, 14 feet from the 160 and 12 feet from the QS8s. It was ARMAGEDDON with astonishing clarity. The most interesting thing is that I measured the peak voltage at one of the QS8s and with an estimate of the impedance, I calculated just over 260 peak Watts supplied by the ADA-1000. I'm pretty sure my Onk can do that but not if it's also feeding other channels.
