Not really, as I'm sure there are differences, but perhaps there shouldn't be any if the design is transparent enough (and the specs do look rather good)?jaxwired said:What you are really asking is, do all amplifiers and DACs sound the same and therefore only features really matter. My answer is no, they don't. For those that believe that hifi amps do sound different, then it's just a question of which ones sound better and how much better do they sound. I have not heard that Yamaha AVR, but I have heard lots of good quality 2 channel amps and these new NAD amps rank among the best I've heard. Much of the cost of a home theater amp like that Yamaha is due to the sophisticated home theater features and the multiple channel support. A 2 channel hifi amp has much more money sunk into quality parts for just those 2 channel.
For some people, a high quality 2 channel hifi can create incredible beauty and take the listener on a moving and emotional ride. This experience is dulled substantially by even small reductions in sound quality. For these people, the NAD can provide this level of involvement and a lesser amp usually cannot.
I get the whole thing of beauty and emotional ride mularky, but I don't think at this price, quality should ever be an issue, merely a difference in presentation and that is not neccessarily better, but preferred by some.
