What is the Sound of Impedence Mismatch?

As I understand it, you want your power amplifier to have an input impendence much higher than the output impedence of your preamp, at least 10x. Can anyone tell me what the sonic symptoms are of a mismatch? If I'm hovering around 10x, what might I hear that would indicate an impedence mismatch as opposed to, say, a preamp that is simply too bright or whatever?

Sounds like the Presence has too much "presence". Which tubes is it using? Sometimes a simple tube swap is all that's required to restore a more pleasant tonal balance...
Of course if you are just borrowing the piece and can't change the tubes, that's another matter.
