Most audiophiles are old and here that is just fact. Older people have significantly reduced high frequency range almost as a rule. Again just fact.
You are literally anthropomorphising an electrical signal not to mention interchanging sound and electrical signals which is a false pretence.
When you pass the very significant ultrasonic content of a typical unfiltered or lightly filtered NOS DAC through a non linear system which all audio systems are especially at ultrasonic frequencies and with tubes, that aliases into the audible band. That is not theory that is simple fact. Also fact that noise / distortion can be pleasing to some and it has been shown, again fact that playing with noise and distortion can give a sense of space that is not in the recording.
Why do want to bad to reject reality.
