Marakanetz,
Can you give us an idea of why you think that will be the case? Have you heard both tables?
I can't comment on the Gyrodec, never having heard one. I did have an Amadeus and quite liked it. But based on my experience thus far with turntables, I'd be wary about statements about across the board "better." To the OP, in what areas of sound reproduction would you most like to hear improvements?
