Legendary audio equipment

I'm interested in getting some feedback on legendary pieces...vintage and the like. I'm not talking "good" or "in my opinion", I'm talking widely accepted legends of the audio world. For example in my opinion, Evander Holyfield is a good boxer, but everyone knows that Muhammed Ali was the all time greatest...an undisputed legend. That's the type of stuff I'm talking about. So I don't want to see Vandersteen or Pass in this bunch, because they haven't been around long enough. Now can someone tell me what the deal is with the Marantz 10b and why is it selling for so freakin much money?
