Tubes and solid-state equipment produce different types of distortion. Solid-state gear produces mostly what is known as odd-order harmonics. Tube gear, on the other hand, produces more of what is known as even-order harmonics. The details of which are fairly interesting and of an entirely different thread. But, it is certain that the human ear prefers even-ordered harmonics (even meaning that each multiple of the fundamental lands within our tuning scale, odd-ordered does not).

Do Class ab amps suffer from even harmonics?
Originally posted by TroyD I am finding this thread incredibly illuminating, thanks guys.
If you could dumb it down for me a little, could someone explain the difference in even and odd ordered harmonics?
At least, assuming that "odd harmonic" and "even harmonic" refers to those
signals which are odd and even multiples, respectively, of the original
("fundamental") frequency. Suppose the fundamental is a 440 Hz "A". The
first two even multiples occur at 880 Hz and 1760 Hz - each "A" in
successive octaves. 6X the fundamental is 2640 Hz, very close to an
E (which is a fifth up from the 1760 Hz A6).
Now look at the odd multiples:
1X = 440 Hz (A4)
3X = 1320 Hz (close to E6)
5X = 2200 Hz (roughly a C sharp - ooops!)
7X = 3080 Hz (not quite an F sharp - oops again!)

Just an observation
