The Benchmark stack is, of course, sonically stellar - from a classic 2 box perspective.
Feature wise, though, I miss the ability to drive a sub and implement a configurable crossover frequency to optimally drive the back-end of the stack. In many real-world situations, the inability to implement a 2:1 system with an optimal xover may well be a more important performance limitation than perfect theoretical performance with full-range speakers (if there is really such a thing, even Magico these days tries to sell you a sub along with their top range towers :-D).
While I have concerns about NAD's quality issues (I am a fan, but there are too many such discussions to dismiss them), I think they are experimenting with all the best feature mixes. I'd love an M-series version of the D7050.
