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

@donquichotte -- 

Have you inquired about this to Sonus Faber directly? 

An important aspect to address is what you yourself can do further ahead to lessen the negative impact time will have on these no doubt beautifully made and sounding speakers. Looking out for proper overall atmospherics, i.e.: stable temperature, humidity levels and keeping them out of direct sunlight will do a lot. Regular use will only do them good. 

Given the above and the assumed assembly and parts quality (incl. the rubber surrounds) of the Futura's I would expect them to last decades, with another 20 years of life span not being unlikely. If Sonus Faber have put longevity limited electrolytic capacitors in the crossovers of these, they should be ashamed of themselves. 

If they're the dream speakers of yours, make sure to acquire of a well-kept pair of them - in whichever way you'd be able to assess this. 

@phusis :

Thank you for your answer! Of course, I did ask Sonus Faber a while ago and their answer was disappointing as far as I’m concerned, they simply redirected me to my local dealer. The dealer, on the other hand, is far from impartial because it’s him I’m buying the speakers from (it’s a buy back pair). Long term, I don’t think I can count on either Sonus Faber or the dealer, that’s why I’m trying to assess if I can take care of these babies without their assistance.

Of course they will be taken good care of in my room: proper atmospherics, away from direct sunlight, moderate listening levels, daily use, quality amplifications...

@donquichotte  - seems you’re avoiding the 2 sources that would be most helpful, like it’s some kind of conspiracy.

There are no guarantees. If it’s a significant enough problem if it fails, like zero funds to fix, then maybe not purchase in the first place.

If it’s a dream item, I’d roll the dice to at least have them in my life for awhile- we only have 1 life to live and enjoy.  

@donquichotte --

The response by Sonus Faber is disappointing, to say the least. Indeed it could keep me from buying their speakers if I had an initial interest, but we’re not talking about my needs and choices considered.

As it is I understand why you’ve been left in a bit of a quandary here. I suspect the Futura’s won’t need any servicing down the line, at least not for the foreseeable future the next some 15-20 years, but I would investigate into their crossovers. The Stereophile review do state the following on the crossover:

The complex crossover is said to feature "progressive slopes" and is realized with Mundorf Supreme capacitors and Jantzen inductors.

I would be surprised if electrolytic caps had sneaked in here, so that’s likely one thing less to worry about. 

As to their regular use, I wouldn’t hold back giving them a little workout now and then.
