«In acoustics, "tone" has two primary meanings:
the perceived pitch and quality of a sound, or a sound with a definite, recognizable pitch, which can be a simple, single-frequency sine wave or a complex combination of frequencies»
By "tone" i guess you mean "timbre" perception...
There is five factors to define timbre in acoustics and i dont think we can judge the timbre translation of your system/room from the original recording through a mic recording from your listening position through youtube and through another system/room (mine) or with headphone..
We can formulate a judgment for sure, a more or less experimented one; myself i think your system/room appear good but not impressive at all ...
You may think my sound system is mediocre ( it is low cost), of course, hence my very relative judgment.
When I want to listen and hear how well any of my systems is reproducing tone, I always turn to jazz recordings:
