Power Amplifier Reviews

This graph shows that the 7500’s left channel, with two channels driving 8-ohm loads continuously at 1 kHz, reached 0.1% distortion at 284.9 watts and 1% distortion at 342.3 watts. Into 4 ohms, the amplifier reached 0.1% distortion at 447.6 watts and 1% distortion at 492.8 watts.

With five channels driven continuously into 8-ohm loads, the AVR reached 0.1% distortion at 260.1 watts and 1% distortion at 301.1 watts. The manufacturer’s stated distortion of 0.03% was reached at 238.7 watts, which is actually higher than the spec'd 200Wpc at that distortion level with all channels driven.
