If you mix audible and inaudible (ultrasonic) content, you might get IMD at some element of the audio chain. For example 20kHz sine wave + 1kHz could create a distortion at 5kHz making recording sound harsh, even though originally it didn't sound like this. Of course it's highly improbable, but I wanted to show, that not always more = better. I think there is no reason to record something we can't hear.
