Sonus faber - Amati suprema?

A typo in my title which this forum doesn’t allow you to edit. It’s the supreme, not the suprema which is the really really really expensive speaker. I have no idea why sf did this so similar I will never get them straight. I hope I don’t order one by mistake instead of the other and have a really really massive bill to deal with

A friend of mine did. He was skeptical that it would sound that much better, but he said it sounded amazing and felt it was probably worth the price. He has extensive experience with high end speakers... Cora, Lillium, B&W, Wilson... etc. 

I’m really torn by your question. I really love my G5’s and don’t really want to have getting the Supreme niggeling me in the back of my head. I already have the question of what kind of differences are there between the Lilium, the Supreme and the I’ll Cremonese and the EX3ME.
When I finally got a SF dealer in my area,  they only had the G5 to listen to and while the sales person tried several times to sell me the Lilium, I wasn’t going to agree to buy before I could try, and they seemed pretty cold on getting a $75K demo.
