Cannot find perfect sound

@enliten - I agree with what you are saying.  After reading all 80+ responses, my conclusion is that the OP pretty much has made up his mind that he will never find a pair of “perfect” speakers, and seems to have a rebuttal for every suggestion!  Experiencing music reproduction in one’s own listening space with one’s own gear is a unique set up and no amount of listening in stores or other’s rooms is an indicator.  OP’s focus on this so called “timing” is stressing him out, and he’s missing the joy of just simply listening to music he enjoys.

You might consider looking at a headphone setup and pass on speakers altogether...no room to bother with 

"Cannot find perfect sound"
And you never will!
It's all an illusion, but get rid of the basic problems and much reward is possible.
Timing issues can be largely removed by using a full range speaker.I have heard Lowther, can't remember the model, sound spectacular on Open Baffle, augmented with OB servo bass and a Raal tweeter introduced at about 10Khz.
Using just a single capacitor in series with the tweeter will do no damage to the timing. This represents a first order crossover, the least offensive, also the ear is not sensitive to phase shift at such high frequencies.

The OB servo bass has phase adjustment built in to the supplied plate amps so no problem there.
Get ready to ditch the earbuds.

There are other fullrange drivers to consider including some expensive field coil versions.

A good pair of grados...would be chasing the dream $

Lol;

Poor Guy.......

I said the same thing 

The new stuff is SO bright, now days 
You hear everything that is not “ just right”
Plus, they play it so frickin loud

When ,  I upgraded one component at a time, I always went to my Grado headphones as the “ reference “ to compare it to.
They do everything right.

Anyway , Now my headphones sound “ ok” and my setup is much better

Who would have thought ?

Speaker -Amp combo is the most important part of chain to get right for the long haul

You need to go to a Audio show and hit all the rooms to find out “ what you like “ first.   Ie AXPONA etc

Start with some cheaper  “ soft dome” speakers vs all the hyper resolving, hyper expensive ; then make changes

Or better yet , find an audio buddy who has it done already 
My guess you’ve not heard it done right..
If your into 80’s rock it will never sound good on the good stuff
