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?

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)
@atmasphere   Thank you for the clear and detailed response. You provided me a level of education in audio that I never thought would be obtained on a forum.
