Naim?

I’ve never heard a Naim amp but would like to. The 500DR amp is only 140 watts a channel and costs 35k!! Also it only weighs 50lbs? What the hell could be in this thing that would make it worth a quarter of that? Also they pride themselves on using what sounds good not what’s necessarily expensive. No fancy casework no bling. So I don’t think there is anything special in there component wise, I could be wrong. This thing costs 700 bucks a lb?? Don’t hear much about naim separates on here what ye all say??
