When I first purchased my Outlaw model 7125 (Power Output: 7 x 125 watts RMS at 8 ohms, all channels driven and 7 x 190 watts RMS at 4 ohms, all channels driven), I noticed a huge difference when plugged in with my Sony STR-DG1000 receiver, which claimed 110wpc. The Outlaw is simply an incredible amp with plenty of power for my needs. I have one question. I have plans to upgrade the receiver to possibly the Sony STR-DA3400ES or Onkyo TX-NR807. Does the power output of the receiver really matter if it will be plugged into my Outlaw amp?
