Do not buy any Sonus Faber used

Phaelon's point cannot be dismissed, and is THE issue at hand, especially for THIS website, a facilitator of USED equipment. Sumiko's policy is clear and broad: there will be NO service/parts for used speakers that cannot be verified as originally sold through a dealer. I understand this for a new speaker needing warranty repair, however, this policy clearly impacts the used community in a BIG way, as I'm sure that many if not most transactions here do not include an original invoice. I'm sure many don't have it to begin with, especially if the equipment has been sold several times, a not atypical scenario here at agon. The OP has it right. Under these circumstances, the used market for SF might be tenuous at best. It should actually collapse price-wise, except for the fact that most used buyers will not be aware of Sumiko's new policy, and even future agon buyers will likely not know as this thread slowly fades away. One thing Sumiko must understand, however, is that a robust used market facilitates new product sales as those wishing to upgrade or change have an outlet to unload equipment for a fair price and use the proceeds to buy new. IMHO, an unnecessary and potentially damaging business decision by Sumiko.
