How does the input impedance of an amplifier effect it sonically?


I understand the effects of an output to input impedance miss-match, but what I don’t understand is
why there’s such wide range in (especially input) impedances. Most tube amplifiers have a very input impedance. Solid state on the other hand has impedances that range from 5-250k. Why so much variance and how does it effect the sound of an amplifier, if it does at all?

If the preamp is struggling, doesn't that affect the amp's output in the bass more than in other regions?  I seem to remember this from John Atkinson comments.
