used Sonus Faber repair (again)


Sonus Faber warns won't assist with repair of speakers not purchased by original buyer. Have any second owners out there had any actual experience trying to get their speakers repaired? If could not produce proof that the speakers were originally purchased from an authorized dealer, did this matter?

Thanks to all

I had no problem getting my second hand SF speakers repaired by Sumiko.  All they wanted to know was that my speakers were originally sold through their NA distribution networks and that they were not grey market imports  Although grey market imports are not illegal, you cannot expect the NA distributor to offer warranty or general repair service for those who purposely circumvented their NA distribution rights. 


Thank you testpilot. I have considered buying used SF in the past, but always scared off by possibility of inability to get repaired if needed.
