Cannot find perfect sound

Since you speak of timing, have you tried horn speakers or similar that uses on driver for most of the frequency range?
Like Avantgarde Acoustics. Should help a lot with timing.

Some speakers like the Kii Three has some DSP functions that can be somewhat configured to your taste. Might also be worth trying.

It’s at the rainbow’s end.
Look for the pot of gold and a unicorn. 

I know what you are saying. However much of what you are hearing is due to less than ideal speaker positioning within the room, room acoustics and listening position.  
The larger high end speakers demand a larger room and with that more problems.  
My personal solution is to setup a nearfield listening position within my larger room using speakers that are designed to be nearfield monitors (Harbeth)
A nearfield setup allows you to place the speakers well away from side or back walls and the listening spot per the typical nearfied triangle is also well away from the wall behind the listener.  
My nearfield setup in a larger room is modest compared to many high end systems but the sound that I hear can better or compete with the best regardless of price.  
The only downside is that the room is somewhat sectioned off, basically you are sitting in the center of the room as opposed to along a wall.  
But for me the sound is more than worth it.  The coherence and imaging are spectacular.  

Interesting - The Skullcandy does not come close to the clarity, deepness and crispness of my DYS Speakers I made myself.  It is not the electronics or the speakers that are at fault it is your ears.  You have apparently a very good ability to pick out details in music and you have your favorite things you like best to be brought out.  Personally I have felt the kick of bass hit my chest and think wow!  Ear buds cannot do that!  You should audition many systems before buying again so you can get as close to what you call perfection.  Perfection may not exist.  At some point you may have to settle for "good enough for me."   What you think is perfect the next guy might think it sounds terrible.  I have a relative and everything sounds like a transistor radio.  His ears really cannot tell. So he will not be spending thousands on a great world renown stereo but will probably buy a nice fishing boat.  what ever floats your boat.  :)
