that's amazing how you can have the same belt for 3 years. I am pretty consistent about breaking a belt every few weeks and I probably only listen for 10hrs a week. I've had 3 different Amadeus too, so I know it is not the table. I've had factory belts, Pranka belts, and my belts all break in roughly the same amount of time.
I went from a standard Amadeus to the GTA. the GTA does everything exactly the same as the Amadeus, but kicks it up a notch.
