AV Receivers

This graph shows that the SR8002’s left channel, from CD input to speaker output with two channels driving 8-ohm loads, reaches 0.1% distortion at 174.1 watts and 1% distortion at 187.4 watts. Clearly, the distortion level is very flat across all power outputs until it gets to about 155 watts. Into 4 ohms, the amplifier reaches 0.1% distortion at 231.9 watts and 1% distortion at 271.5 watts.

With five channels driven continuously into 8-ohm loads, the receiver reaches 0.1% distortion at 119.0 watts and 1% distortion at 133.8 watts. With all channels driven continuously into 8-ohm loads, it reaches 0.1% distortion at 109.1 watts and 1% distortion at 117.7 watts. The power specs do not specify the number of channels driven, but at 125Wpc into 8 ohms with less than 0.08% THD, they are not far off the mark.
