Impedance Matching Preamp/Amp Assiance Pls?

I'm looking to purchase a Cary SLP-05 that has an input impedance of 100k Ohms (XLR) and a gain of 27db. My Spectron MK2 has an input impedance of 50k Ohms using the XLR inputs (which I use).

What is the consequence of using the Cary with the Spectron regarding its compatiblity relative to the impedance and gain specs? Any issues I should be aware of?

Thanks in advance for your comments.

Thanks. Can you explain the 10:1 rule? 10 X 400=4000 ohms and the input impedance of the Spectron it 50,000 phms. So I'm not sure I understand why everything is ok.

Also, can you provide me an example where impedances don't match well and the consequences?

Thanks again.
