Isn't the H/K Citation 2 on that list? I would not regard that as an old-timer's issue- that amplifier *is* pretty significant- it has wide bandwidth, low distortion and decent power (for the day), and if properly refurbished keeps up with modern amps with no trouble at all. Today they are commanding very decent prices, always a good indicator. If you look around you can find a lot of today's amplifiers that are a tip of the hat to that design.
History will be the judge on the current crop of class D and the like. I would not be surprised if those amplifiers will someday be seen as significant as well.
