Why do we want to distortions?


So I read, Tube amplifiers sound better because of the euphonic distortions they add to the music.
I thought we were trying to avoid distortions.  What makes euphonic distortions sound better?

Tubes when they do distort its smoother even order harmonics most solid state are odd harmonics . That being said mosfets, bipolar, Jfets have tube like characters . Tubes do add bloom 
Especially specific power tubes like 300 Bs  but have excellent midrange sonics.
@bdp24 sorry, my poor choice of words, You are not mistaken, it was just an understatement IMHO

Because some distortions sound better than the original.

It is like adding MSG to food......
@atmasphere Thanks for that lengthy description. I emailed that one to myself for future reference. You never know when Audiogon will delete this thread.

I have 4 types of gear and they sound different but smooth. Your post may explain what I am hearing.

- KRELL K-300i (Class AB very smooth and powerful)
- Benchmark HPA4 + AHB2 (extremely clear and smooth)
- D-Sonic M3a 800s (Class D smooth and powerful)
- CODA 07x preamp (SET smooth)
