My last receiver, an Aiwa AV-DV75 burned up (power supply bit the dust), and I'm looking for a replacement but finding high power home audio gear next to non-existent anymore. I used the Aiwa in two channel mode which in that mode provided 170 watts RMS per channel both channels driven. That was adequate. I replaced it with a smaller unit that is 120 watts RMS per channel but doesn't really do an adequate job, in particular my speakers impedance tends to take a dive at around 45Hz so an amplifier that can't drive adequate current just wimps out on the bass. I'd like to find something in the 300 watt per channel range but except for automotive gear this power level appears non-existent anymore. Anyone got any recommendations?
