This graph shows that the RR2150's left channel, from CD input to speaker output with two channels driving 8-ohm loads, reaches 0.1% distortion at 125.1 watts and 1% distortion at 145.9 watts. Into 4 ohms, the amplifier reaches 0.1% distortion at 220.7 watts and 1% distortion at 243.7 watts.

THD+N from the amplifier was less than 0.011% at 1 kHz when driving 2.83 volts into an 8-ohm load. Crosstalk at 1 kHz driving 2.83 volts into an 8-ohm load was –74.77 dB left to right and –75.39 dB right to left. The signal-to-noise ratio with 2.83 volts driving an 8-ohm load from 10 Hz to 24 kHz with "A" weighting was –99.42 dBrA.—MJP
