Quite often, differences between solid state amplifiers and tube amplifiers
are scientifically measurable.  The amplification curve (x-axis = input
voltage, y-axis = output voltage) of tube amps are often far from linear,
and results in significant amount of harmonic distortion.  While not
scientifically accurate, the effects are audible, and often considered
pleasant.

As for the $50/ft speaker cables, I must say that its effect was
intelligently designed.
