I have just bought the M55, M25 and M15 after auditioning them at a local HIFI expo in the city I live in.
I guess that you could say I fell in love with the 'musicality'?? if thats a word, of the NAD components.
I had the luck to hear them playing through a pair of Gradient revolutions, which I ALSO ended up purchasing as a result.
I know that a lot of the perceived performance of equipment gets down to where you hear it and under what listening conditions. But I was fortunate enough to be able to move from room to room in a large mansion where the show was being held, listening to speakers and components from manufacturers like NHT, Moon, Musical Fidelity and CreekDestiny.
Myself and my two mates who tagged along to ensure that reckless spending occurred, all agreed that the setup with the NAD matched with the Gradients was one of the most outstanding setups we heard that day.
I spent a lot of time going in and out of those rooms, looking for reasons why that setup sounded better then many others there, including (incredibly) a set of Martens! Maybe it was the room size, the fact that there was a little more 'angles' in that room from non parallel walls etc. I don't know. All I can say that it was so good it prompted me to fork out just under 15,000 euros for the same setup with 2 Gradient Preludes thrown in to the mix for my middle speakers.
Suffice it to say that you would be hard pressed to go wrong in choosing the NAD's. I recommend them highly.
