How to match preamp and power amp?


How to match them by looking at the preamp output impedance and the input impedance of the amp? Any magic numbers? I don't understand their relationship. Please help.

So, my power amp specs indicate an input impedance of 100 kOhms, and an input sensitivity of 2.71 Vrms.  The amp has only XLR inputs on it.

Would I be correct to assume that most SS pre-amps would work well?  The pre-amp I'm researching indicates an XLR output impedance of <160Ω.  Thanks!
The pre-amp specs I'm researching indicates:  XLR Maximum output level>22VRMS.
The power amp is a Krell FPB 400cx.
