Preamp/Amp impedance mismatch

I'll apologise up front for this 'newbie' question!

I have Channel Islands Audio D-100 monoblocks, with a rated input impedance of '100k ohms'. I am considering a Linn Kolektor preamp to go with them. However, the Linn has an output impedance of '300 ohms'. Is this going to cause any sort of problem?

Thanks.
