Your thoughts on the AX2 are the exact same as mine. In fact, I purchased AX2's, went to pick them up, and the dealer did not have them! I went nuts, and he offered a deal on the AX3, for the AX2 price. I listened to them, liked them better and went home happier!
I would suggest taking some of your favourite music with you. Insist on listening...and YOU drive the volume. Also some dealers are connecting subs, simply because the dealers in this market/category are selling HT. Ensure a sub is not connected.
