Fidelity vs. Musicality...........Is there a tug of War?

Define what is "musicality" and what is "fidelity."  

Be very specific and use objective terms, not subjective terms.  

Once that is finished and resolved, then we can discuss why some equipment fails to reproduce musical performances and other equipment comes very close to "you are there" reproduction.

One can put together a system that measures really well but in the end, it’s not an oscilloscope that’s going to listen to the system-- it’s individual human beings, whose perception of sound and aesthetic preferences can vary considerably, to say the least.

Agreed

Everybody will have their own definition of what fidelity is, but to me fidelity does not equal measuring well on a scope. 2nd order harmonics is not distortion, 5th order harmonics is. 

Fidelity in audio is faithfulness to the reproduction of music, not faithfulness to reproducing a sine wave on a scope. Measurements that give the average deaf engineer wood is of no consequence to anyone with an interest in audio.

2nd order harmonics is not distortion, 5th order harmonics is.

Anything added is distortion.  Piano, for instance, has overtones stretched over harmonics.  Octave higher key is not tuned to double frequency but to overtone of the lower octave key (otherwise keys would beat).  Tuning person is winding strings up until beat stops.  Because of that piano has accumulated error of about 30 cents at both ends of the keyboard.  Playing piano thru amplifier that adds second harmonic, is creating beats - exactly against tuning to avoid it .  With overly warm gear piano can sound even like out of tune.

Everybody will have their own definition of what fidelity is ...

What’s wrong with the commonly accepted definition?
fi·del·i·ty noun: fidelityfaithfulness to a person, cause, or belief ...sexual faithfulness to a spouse or partner ...the degree of exactness with which something is copied or reproduced ...

There’s no reason to make this more complicated than it is. Conversation is impossible if we can’t agree on simple terms.

2nd order harmonics is not distortion, 5th order harmonics is.

Anything not present in the original is distortion, by commonly accepted definition.
