Does "Fast" = "Detailed"?

I've noticed a few people discussing "fast" as an adjective for systems and components. A couple friends of mine use fast as an adjective they look for in amps and speakers (and other components including wire). I've noticed in my limited experience that those who like fast systems also tend to own/favor highly detailed systems. Recently, I looked at a member's system, which includes speakers built with ribbon tweeters used in conjunction with NuForce amps. He mentions liking a fast sounding system. Having heard both ribbon speakers and NuForce amps, I have an idea that this system is quite detailed.

Does "fast" equate to "detailed"?
