Best Amps or Integrated on measured performance

According to you, what are the best amps, solid state and tubes, integrated or power amps, based on their measured performance?

I am one of those who reads Atkinson's measurements. I know it's sad to admit it, but it gives me piece of mind that the gear I have performs well on the bench...

If those bases are covered, then, I listen to the equipment. Don't get me wrong, of course many times I go and listen gear that someone has recommended me strongly - but knowing that the amp has low distorsion, or high signal-to-noise ratio, or no negative feedback, Class A, etc is something that raises my interest.
