"I'm sure with the right $$$ you could have one speaker with all the desired characteristics, but I am not in that boat, and within my affordability range I can't have it all. So I keep both planar and cone-type speakers around."
FWIW, I was in the same boat regarding pereference for planars versus box designs for different genres. The cost effective solution for me turned out to be the OHMs. Cost ranges from $1000 to $5000 depending mostly on room size.
