I want to buy an Audio Interface and Condenser Microphone to record to my PC. I found the two following matching my needs:

But according to several Audio-related sources like e.g. mynewmicrophone.com the Load-Impedance of the Audio Interface should be at least five times higher than the Output Impedance of the Microphone.

SSL 12 Specs say it's mic input has an impedance of 1.2 kΩ and the homepage of the OC818 states that it has an impedance of 275 Ω. This would be a ratio of only ~4.36. This is less than the often recommended 10 or even 5. How bad would that be?

The Specs of the OC818 also state that only Load impedance of "> 1 kΩ" is required - which would be met in our case - but how much would be the influence of being under the generally recommended limit of having at least five times the impedance?
