Sonus Faber Minima Amator compared to Minima fm2?

Hi Guys, I’ve searched everywhere but can seem to find a comparison sonic-ally between the original Minima Amator & fm2. The specs show that the Minima doesn’t go nearly as low, but does have the esotar 330 tweeter. So maybe it has a thinner yet sweeter sound? Also I can’t seem to find which one Franco Serblin designed first & why he designed two different versions of the minima? Any input on this would be greatly appreciated. Thanks in advance!
