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"?

I agree with Bob aka Inpep's comments to a certain degree. That is, loudspeakers are most certainly the lossiest part of the reproduction chain, even the very best that we have available to us.

Having said that, loss is loss and minimizing it can only improve the linearity and reproduction of the system. If such were not true, component changes would not be nearly as audible as they are in even a reasonably resolving system. This is kind of like having a leaky faucet at the end of a leaky hose. Fixing all of the leaks in the hose will deliver more of the content to the faucet, which is still leaking. Now we have a "controlled leak", but the losses are minimized ( and expected ) at that point.

I can remember the very first time that i heard a "fast" system. I was listening to a recording that i had heard hundreds of times. At one point, there is a stop in the music and a huge surge of dynamic energy from a drum strike starts the flow of music again. With this system, that drum strike had so much speed, attack and dynamic energy that it literally startled me. By "startling me", i mean that i literally jumped out of my listening seat onto the floor in front of me. I am NOT joking about the difference in intensity of the reproduction OR my re-action to experience something like this.

Not only was that level of energy and type of reproduction an eye / ear opening experience for me, but also for my Brother. The funny thing is, he just mentioned this system / experience to me two days before Tvad posted this thread. This came up because he knew that his current system lacked speed, therefore losing resolution and dynamic impact. Sean

Sean,
Can you tell us what this system was that made you jump out of your chair when the drums kicked in?
