Hooray for NAD, for trying to curve their approach toward the future and without selling their soul like another company around here.
I think that NAD relies on the fact that their receivers are considered to be above mass market and that their performance with complex loads on average is better than competing models from other manufacturers. This could be different on the T 747 as we haven't seen it on the bench yet. They, like many other manufacturers, may have sacrificed performance for features. What is what is hard to tell, we'll have to wait and see on this one.
