+3 for Vandersteen.
You should also check out Zu Audio. Used, you can find a nice pair for around $1K. I own the Union and the Omen Bookshelf, and am very pleased with the sound quality. (Though I would avoid some of the models with Ribbon Tweeter, they didn't last very long in production).
I agree with paraneer, you should go around to as many dealers and just listen. Once you find your 'sound', you will know where you want to go.
Oh yeah, the Zu's are super efficient and your NAD would have no problem powering them.
