Hey RL..........I think that NAD is a good product. I too owned them in the past. But "strong, ballsy" is a bit much. Amps that are ballsy double their RMS power from 8 to 4 ohms and then again at 2 ohms. The NAD doesn't come close. Note the specs on the NAD page talk about its "dynamic power" at 4 and 2 ohms and even that doesn't come close to doubling. Lets call a spade a spade. NAD is a very good mid fi piece. Nothing more.
