Does "Fast" = "Detailed"?

Here's a good exapmle. I have a JOR. The Jadis stock tubes are KT90's. I decided to replace them with the Electro Harmonix KT88's. The 88's were like sludge, boomy, its was like the music was comming from the speaker like paste in a "tube". The 90's are detailed, sharp, vivid =fast. Anything that is not "fast' I refer to as grainy/smokey/hazy/dull. All 3 components can be subject to this "slow/dull" sound. The cdp, amp, speaker xover all 3 can be wired funky and thus the sound goes around in circles , too many circles, before it makes its exit to your ears. A good quick amp, vdp. xover will channel the music most intelligently/musically.
Now do you have the ears to tell the differences? Most folks make claims they do.

does 'detailed'='forward'?.....as far as warm,fast and detailed, i default to the two out of three rule....any combination of the two but never all three.

Gunbei,
"Is detail then as Puremusic mentions limited to the frequency domain?"

No, detail (the noun) is not limited to the frequency domain. As I mentioned in the second paragraph in my post above, "It takes a high level of detail in all three domains..." However, as best I could tell, the adjective "detailed" refers in most (but not all) discusions to the frequency domain; namely, the level of resolution of the harmonic details (as opposed to temporal or amplitude details). Musical Nirvana (as well as the devil) is in all the details and how faithfully (or unfaithfully) they are reproduced.

Tvad, Thanks for your kind compliment.

Like having contracting work done. Good, fast and cheap. Pick any two. You can't have all three.

A friend that had the Audio research VLT200 said my JOR was more detailed/refined/precise/accurate/fast. All mean the same thing. A cdp can ve fast, a amp can be fast, a speaker can be fast. But really fast is misleading. A ss amp most likely is faster than the tube amp, but a high quality tube amp 'cooks ' the image before releasing it to your ear. Thus a tube amp developes the digital signal, adds softness and life to the image. Provided the speakers can properly process tha signal. If a speakers voice coil and or its Xover nert work is not on the same level as the amp's output, the end result will be the speakers distorting what the amp gives.
Likewise the signal from a cdp ,if too cold/lacks life will then alters what the amp is capable of producing. All 3 components muct add their share to the equation, the end result will be a fast/accurate lifelike soundstage.
Size of the system has absolutely no bearing on lifelike sound stage. Tyler's tiny 2 ways with the 5 inch midwoofer can produce its own modest soundstage as opposed to some gigantic speakers with up to 6 drivers/cabinet that on soundstage quality scale , 1-10, I give a zero.
Feel free to disagree, these are my findings after 30 yrs in researching stereo equipment.
