Mmm, K, class let me see if I can explain this so even SVI can understand it.

Distortion, bad, mmmmm, K
Less distortion, good, mmmmm, K

"Well, why do they have 10% distortion if it's bad"?

Well Cartman, some people don't have a lot of money, mmmm K, let's say, like Kenny, so they have to buy cheap stuff and in order for it to be sold cheap the manufacturers use cheap parts and the result is not so good sound and more distortion.

" My friend says he likes distortion"

Well, Kyle, your friend is a dumbass, mmmmm K.

Let's put it this way for your friend, does the finest gear available have 10% distortion? No! mmmm K. If you were tuning in a radio station on an analog dial would you try to find the clearest sound or would you leave it in an area where all the static could still be heard along with the music?

So terms like "clean" and "clear" are associated with sound without distortion,
mmmmm K

So class what did we learn about distortion?

BAD!!!

Correct!
