As for powering a 4 ohm load the NAD should be fine, as specs go down to rated 2 ohms.
It is all in how the amp sounds to YOU.
As an aside, not many audiophiles have any interest in the NAD. What taht says about NAD I cannot explain.
The retail $2,800. is a lot to just guess at it working with your speakers.
You really need to convince the dealer to allow a home demo, so you can actually decide.
Without a home demo, I would have to pass.
I have Bryston with my Maggies.
And plenty of used good amps out there which have been suggested with Maggies.
