Fourier Amplifiers What Is The History and How Reliable


Happen to be considering a pair of Fourier Panthere amplifiers and am wondering what the history is on them. Supposedly these are some of the last production models and are more reliable than previous versions. 

I have never been an OTL owner and would use them with a pair of JBL 4365 speakers. I know the earlier version of OTL amps such as the Futterman were not the most reliable of designs, and they tended to fail catastrophically. Or at least that is what I had heard of. 

How reliable are the Fourier? I understand the company is out of production, how would one get them serviced? 

I see they use a closed case and forced air fan, what are ventilation requirements? 

Are they worth spending money on? Or is it more akin to own a vintage English roadster or Italian sportscar?
