I am a tad confused here... Because you can have revealing and very detailed speakers like Sierra with Raal and have them still be colored...warm, dark, etc.
I think what your asking is ... Do you want the detailed turned up so high on a speaker that you hear every nuance good or bad or do you want the a speaker to be less detailed but more forgiving on source material.
As with everything here that is a matter of personal choice and depends very heavily on the source material you tend to gravitate to.
There is no "right answer"...
If asking me...I would want a speaker that is capable of being as detailed as I like and one that I am able to adjust using various methods at my disposal to make it into anything I like. If a speaker lacks the ability to be that detailed there is almost nothing you can do to give it that detail...but taking it away with a few AVR / Receiver tricks is not all that hard.
Same question was..and continues to be asked about HDTV definition... currently, on a good TV set, you can see an actors wrinkles, their makeup, their imperfections...as we move to 4k that type of detail can disrupt the viewer's "suspension of disbelief"... Is this a good or bad thing?
If we go back and watch Star Wars do we really want to see enough detail to tell the Wooky was clearly in a gorilla suit?
Either way I think it pushes new content to be even better...
But I go back to their being no right answer.
