It definetely took me a while to set up mine properly, and even after some time thinking that it was perfect I found new ways to make it better, or closer to what it should sound. Getting the golf ball centered in the cup and the azimuth is not really easy. After some stress I did it by letting the silicone cup fall unscrewed so it stays aligned but no touching the golf ball. Then try to look from the centred top of the ball and centre it. After that reposition the sili cup up so the ball is not too dumped. After the ball is properly centred everything gets easier, just don't forget to maintain VTA level when centring it. And if you haven't already, try the double grounding as explained in a thread in this forum, huge difference. I have a GTA so I don't know if these tips will work for the other amadeus models but I believe yes.
sorry for my english
