Well Tempered Amadeus Options

Hi Guys, As I'm avid WTL Classic fan and have owned over three different versions since '93 ending with a Classic MK V version last year. But after having a chance to hear the Amadeus at Don Better Audio in Cleveland Ohio this past November I've come to the realization that had I heard this table in Feburary of said year I know what would be residing on my stand right now. But my question is ask I only intend to do this one time.............., I'm in the position to get either the standard white ball version or the more upscale GTA version with the alumium plinth and black golf ball attachment that cost $3.700 here in the States where the basic one goes for $2.850!, as I've been following the trends here regarding this table in general I'm merely wondering which route have you guys taken?, and if there is in fact a better sound being rendered by the more costly unit?, or is it purely based upon overall appearance and little if anything to do with better Fidelity?. I merely wish to go this route one time and be done with it, so your opinions with more then likely be weighed quite heavily I might add. So fellow WTL owners please share your tales and tell me what's what!. Regards, Oscar
