Genesis 350 vs. Carver AL-III

I currently own a pair of Carver AL-III, my AL-III high frequency roll off above 18kHz and the low is not very good. I am thinking to buy a pair of Genesis 350 to replace to Carver in the next 2 to 3 month. However one of my friend told me both speaker ribbon drivers were identical, although I can't personally confirm that and if this is true, exactly how much difference am I going to get for my money?

Any input would be nice.

Thanks
