LOL - Yep, he loves your wife and hates you. Amazons, especially males (sounds like a male to me) can be very bipolar that way, sweet and loving with one person and nasty, nasty, nasty with another.
Personally, I would not try to get him to like me too hard. I would open his cage when your wife is not around and just don't do anything but talk to him from a distance. Don't ask him to step up, don't offer him your arm or your hand but continue offering treats even if he uses them to displace aggression (what you described is typical of this behavior). Male zons are not known for patience with 'competition' and that's what you have become: competition for your wife's attention and love. Wait him out, he will calm down in the fall provided he is kept at a strict solar schedule (it won't happen if you don't) and, eventually, he will accept you as a flock member but you will need to be careful about not kissing or hugging your wife in front of him because, as far as he is concerned, she belongs to him and not you.
I have three male zons that are hands-off, two are fine with me, will take treats from my hand and I can take the plates and bowls from in front of them and they will not bite or even lunge at me but the third one, Pedro, is a nasty son of a gun and I have to be careful and warn him when I am going to put my hand near him (I say: "Excuuuuse me, excuuuuse me" and, if I see him moving, I go "Be nice! Be nice!" ) and even though he would not bite me, he does the same as yours: fan his tail, erect his neck feathers, pin his eyes and 'take it out' on whatever is near him, attacking the object mercilessly while keeping his eyes on me all the time like saying: "See? This is what I want to do to you!" LOL But, as bad as this might sound to other people, it's actually a great improvement and only happens during breeding season. He used to attack his previous owner and me (when he first came) relentlessly, flying out to bite my face. He sent his previous owner to the hospital three times, the nasty thing... So yours is actually not that bad, taking into consideration that you just got him a few days ago and has no reason to trust you yet. Was his previous owner a man, by any chance? Could he have been abused by him or, if it was a woman, his boyfriend or husband? Because if he was abused by a man before, there's your answer.
So, take your time and just avoid at all costs getting bit (this is VERY important because you don't want to start a trend here). Once he realizes you are no threat to him, he will calm down and, once he is not showing any more displaced aggression, you can start training him a bit and see how he does with it.
