(and it went into protection mode when being tested for 4 ohms ) Denon AVR-2307CI $800, rated power: 100 watts two channels driven (out of seven). Bench test: one channel: 140 watts, five channels: 86 watts. (no trouble driving 4 ohms) Onkyo TX-SR504 $300, rated power: 75 watts two channels driven (out of seven). Bench test: five channels: 72 watts. (and can drive 4 ohms)
