Ars Sonus Filarmonia Reliability

Anyone owning or have in the past has owned a Filarmonia; please outline any functional problems or repairs that you have had to the integrated. Or If you have had a problem free unit, please advise.
I am particularly interested in the SJ model but info on any model would be helpful. Please include the age of the unit when it required repairs, or in the case of care free units, the age of the integrated. If you contribute to this discussion, please advise if you are a retailer, distributer or currently have above referenced integrated for sale.  
Thank you
