Listening Room or Components or my ears?

Your description makes the room sound like a problem.  I can surmise you have one wall that is +/- 21 feet long, but not much else.   A lot of reflections off walls with paneling.  Have a look at this site and see if you can select an area of the total room that could give you better H x L x W.  Then consider some low cost acoustic  wall treatment.  They say the room is 50% of the sound.  I would start there.  Cheers.   https://www.acoustic.ua/forms/rr.en.html  

Agree with the advice on treating your room including adjusting the speakers toe-in and your listening position.  Focals can sound a bit harsh or sibilant especially if you’re sensitive to sibilance.  You may want to demo speakers with a different sound profile if the room treatments don’t work.  You may prefer speakers with a rolled off top end instead of an elevated in room response. 

Six feet is very close together.  Can you move them apart and toe them out more - get out of the tweeter's death ray?

See an audiologist first, if you want to avoid or postpone a wild goose chase.

My suspicion is that the Focal speakers are the biggest culprits for your treble character.
