Please save me from an expensive mistake! Sonus Faber Amati Futura longevity concerns...

@mgrif104 It stabilizes dome vibration to minimize distortion at high volume, which also helps to extend frequency response.

I am not qualified in any exceptional way to answer, but I feel that your worries may haunt you even if nothing happens. I would be wondering why they replaced the woofers and what kind of life they had before going back to the dealer. On the other hand, you may not be like me at all. I once had a Porsche Boxster and because it had a chance of total engine failure, and if it did fail, I would have to pay for it because there’s no dealer coverage or anything, I ended up selling it because all I did is worry if it might fail. I read too much maybe but I just felt like on a teacher salary I could not afford such a thing. Maybe your instincts are right and you should keep looking and see if you can find some sort of giant killer that would work for you. But, if you are definitely in love with this and know that it’s the best thing for you then maybe you should go for it. But do you listen to your inner voice especially if it will not shut up after you buy them. I would hate for it to take your listening experiences because you have to be concerned about the future. And then these days getting any help at all from dealers or manufacturer, seems to be difficult. But again that’s just my two cents and they may not be worth even 2 cents. I appreciate these real world types of posts, because these are concerns that I think many of us struggle with. Good luck! I hope you get Audio bliss in whatever direction you go!

Anything made today will last decades as long as you have ample clean power to not put the drivers into distortion for long periods I own Sonus Faber s and owned 2 before that high build quality .

This is why I have two pairs of original ProAc Response 2's, with back up drivers purchased before they became unobtainable. ;-)  A friend of mine recently bought a used pair of Response 1sc's but he called ProAc to confirm that they do still have replacement drivers in stock, which they said they do.

I'm a little surprised that SF won't confirm the availability of replacement drivers, but then they don't make a dime off the used market.

Crossovers with film caps are not going to ear out, so forget about that.  And anyway, replacing the film caps would not be an issue.  You say the woofers have already been replaced.  Regarding the tweeters, I don't know anything about them but it appears that replacing the ferrofluid is not a big deal.  I think you're getting too concerned and that you should proceed and enjoy them for as along as they last, which should be a good long while.
