Headroom Notes

140 W into 8 ohms, full band, 0.05 % THD, two channels driven, across eleven channels. The rated-output table is identical, condition for condition, to Denon's AVR-X6800H - the two are built on the same platform by the same company, and the amplifier section publishes the same numbers.
