Probably very few people have heard the M2. It's too new to the market. However, there is a used one for sale right now. You could snatch it up and always resell if you don't like it. You'll likely get all your money back.
I'm a huge NAD fan myself. I was using the top of the classic range for quite awhile (165/275). That is one sweet combo and punches way above its price. A LOT of a amp for the money. Plus a phono stage.
I've switched to Bryston, and I'm very happy. I think Bryston would fit your requirements. You can get great deals on Bryston here. There's a BP6 preamp for $900. That's 40% of reatail. And many amps to choose from, all at great prices...
Good luck :)
