Does "Fast" = "Detailed"?

Both fast and warm is possible but unusual.My Supratek Cabernet preamp is both.I had a Metaxas Marquis preamp prior to this that was fast but not warm and all other non Supratek valve preamps I have tried are warm but not fast.
In a way many electrostats are fast and warm through the mids and highs but not so fast through the bass.
The gainclone type chip amps are very fast and when combined with a fast but warm preamp the overall sound can be both warm and fast.I have never heard a SS or digital amp as fast as the Gainclones so for people wanting speed and dynamics these are worth a try.

gentlemn, if there is a rolled off treble, there exists subtractive coloration.

depending upon the dip in the treble, there may be a loss of information.

one may miss certain low level musical details becuase they are recorded at a lower spl , because of the roll off.

thus, the warmth which is consistent with a roll off may eliminate some detail(S) on a recording.

can such a stereo system still be described as detailed ?

it would depend upon how one defined the term. no stsereo systems are perfect, so the designation of "detailed" already assumes that there exists something short of perfection, but how short ?

another words, how much loss of detail due to a dip in the treble still qualifies as a "detailed" stereo system ?

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?
