Matching solid state amps with tube based pre amps

JFC… If the output of the preamp is 100-1000 ohms, and input impedance of the power amp is 20k to 100k ohms, then what is being matched? (Or what needs to be “matched”?)

What does “matched” even supposed to significantly? What is the meaning of the word Ing the sense that it is being suggested?

I have never had a problem with a SS pre s driving SS or tubes amps.
And also never had a problem with a tube pre drinks a tube or SS amplifier.
But maybe others have?>

Given no impedance mismatches,

Tube pre --> SS amp --> sensitive speakers = easy meat
Tube pre --> Tube amp --> sensitive speakers = musical easy meat
Tube integrated amp --> sensitive speakers = theoretically optimal, no worry over impedance matching.

All I think I know, or ever expect to learn. 

I’m running a Pass Labs XA30.8 with a JJ 243 tube preamp and love the combo.

but what if i am a vegetarian?

I’m running a BAT VK50-SE with an Orchard Audio StarKrimson Ultra GaN FET Amplifier. I’m done. No more searching for the Holy Grail. I haven’t found it but this is close enough for me.
