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.

Ok - So I have a Copland CTA301
    Output load 2. 8kohm
     Output voltage (at the time of 47kohm load) Rating: 2V Maximum: 50V
 And Caspian M2
   Input Impedance 38 kohms
    Input Sensitivity 240 mV rms

Would that work?
