You are making the mistake in thinking that because an op-amp provides
linear amplification across a wide range of frequencies it produces the
'nicest' sound.

The human ear is not a linear receiver ;)

It is simply down to what you like - and valves colour the sound in a
way that sounds 'nice' to most people.

Have you ever heard music out of a whirlitzer - hopelessly coloured but
somehow good.

Feel free to disagree - I've been known to be wrong!

Truth in advertising here ( while listening to a tube amp here )
is that most sales are towards a amp with the most power out into
a resisive dummy load.

1) Real speakers are inductive not a 200 watt 4 ohm resistor.
2) Lots of feedback is used to keep a transistor amp linear.
3) Sine waves in a lab is different from real music.
4) People buy amps to be loud for loud rock music.
