You're right. My fault, I usually pick up on that. I've had great success with the audio refinement and B&W (CDM 1NT). I've also had great success with the A3 and signature 805's)
I guess it depends on how much you want to spend. I think the AR could be a big improvement over the NAD, although they are the same power rating.. The A3's can be a little tricky to find. I wouldn't mind grabbing one myself. The AR's are a little easier and should be 100 to 150 dollars cheaper than the A3.
I can't speak about the 3.2 as I have never owned it, but would love to try it.
Honestly, in your situation, I would go for the A3 if you can one used.
