Bright is a bad thing. Its a coloration.
Detailed is a good thing.
Quite often the two are found together. This gives detail a bad name!
Its possible to be extremely detailed and yet quite relaxed. Brightness is often not an actual frequency response error; instead its often caused by distortion (particularly in solid state and digital but can manifest from tubes and analog easily enough) which the ear converts into tonality.
By adding brightness, this can cause a system to temporarily seem more detailed. But in time it will be seen for what it is- a coloration, and not a very pleasant one.
This is just another way of restating what Spencer posted above.
