I also prefer having an amp with a low pass filter, as that allows cascading of the filter slopes of the AVR and sub amp.
      I agree unless your requirements are such that you need over 1kW RMS. At that point, plate amplifiers may start to become prohibitively expensive. Dollar-per-watt, I feel there are advantages to going to a high-power class-D "pro audio style" amplifier when you need over 1kW RMS. And yes I'm talking about music, not movies LFE.
