Have to completely disagree here but all the parameters need to be
measured that affect human hearing. Usual distortion measurements are
not enough.

One parameter that isn't usually discussed is the damping a good
amplifier output provides to a set of speakers.

When a speaker is hit with an electrical thump (high frequency edge)
it tends to resonate and reproduce it's natural frequency on ringing
basis. This produced an induced voltage of very low magnitude. If a
long or poor quality cable is used that isolates the absorption effect
of a good, low impedance, amplifier output from the speaker the
damping is lost and the sound gets muddy. This is equivalent of
removing all the acoustic damping material out of the back of the
speaker enclosure.

Once again: It is fruitless, if not impossible, to compare the
non-linear, physiological properties of human hearing to a instrument
signal analyzer ... period, zero, zip, nada ... any comparison simply
does not _scientifically_ equate.

If, given the same inputs, there is no attenuation or
amplification or distortion in the wire that is discernible, then the
output will be indiscernible audibly if that input is converted to
sound
by the same speaker.


"If these higher frequencies are not passed through any link of the
audio chain (including the cable), the lack thereof will most
definitely
degrade what it was _intended to be reproduced_ for your hearing
enjoyment."

Not at all difficult to comprehend.
