To my ears the outlaw 2150 out classed the nad in sound quality and it may well be the one of the amps to beat in the under $ 1000 dollar price range. I have also compared it to the magmun danalab receiver which was more extened in the high frequences, middle range about the same hard to tell the difference, bass frequences outlaw had the edge.
I also compared it to other highly favorable amps, the outlaw was not outshined as one would think. go figure
