If I correctly understood the link that Kijanki so kindly provided, the$650K/pr. Pivetta mono amps provide 20,000 WPC. This is just a bit over $30 per watt/ch. I'm not sure that this is costly enough to qualify as true "high end". Many a bargain priced 100 WPC amp (equivalent pricing is +/- $3200) would be denied admission to the purist high end club - so I don't know why the Pivetta gets a free ride.
So, Kijanki, maybe not ALL the amps on that list ;-).
