Today I finally received my nad 2700 , I currently have the 2600a . My plans were to bridge each amp to power my RTA15tl speaekers. I turned the volume on max on both amps and then used my yamaha a/v as the master volume. So immediately i noticed my 2600a plays louder than the 2700. I have to set my 2600a a little over 1/4 of the way to get the speakers to blend together. I did everything possible to pinpoint the problem, I even tried both on 2ch instead of mono and I achieved the same result. I tried powering each speaker with each reveiver and again the 2600a still plays louder.
So my question is, is the 2600a just made different where the signal is boosted more than the 2700 or do I perhaps have an issue somewhere with the 2700? The sound quality is the same both amps sound great , I just have to turn the volume up a lot more on my a/v unit when using the 2700 opposed to the 2600.
Also I get a lot more static noise out of my 2600 when the volume knob is turned up to max than with the 2700. (this is of course when no music is playing just volumes cranked up)
