First: i cannot judge from youtube ...
Second: It is a common place fact in small room acoustics that we tune our room from the listening chair position...
Third: I am with you for the brain work over price, but acoustics of small room using mechanical devices and /or DSP and psycho-acoustics is fundamental not a cherry on the cake of well done gear design sorry.
it is the only thing i learned as audiophile...
In any small room the sound perception at the listening position is conditioned by basic acoustics knowledge. Design matter but less than acoustics. I can use a low cost System with optimizing astounding result in a room designed acoustically for it, but i cannot do anything with a high end system in a bad room (most uncontrolled room are not ideal to some degree )
By the way i may use A.I. for speech clarity, but this fact i learned it myself in a two years tuning process with a grid of 100 Helmholtz resonators specifically located.(and other tweaks rooted in acoustics principles )
I dont need a doctorate to understand basics...

Merry christmas to all audiogon friends...
I wish a good health to all ...
And an imprevisible gift for you from God...
@mahgister your assessment of the two audio recordings parallels mine. The reason that I wanted you to listen to this comparison, which I mentioned a couple of weeks ago that I would post, is that this demonstrates that the only thing that matters in the end and that should be judged is the composite resultant sound at the listening chair position.
