Exactly this. It all happens inside.

I’m sure the Vandenhul cables are great. And at least you can buy the cable and make up the lengths you need. But unless you are replacing the wiring all the way through your house the effects they mention are no going to be happening. What is going to be happening is the filtering inside the unit’s power supply once it becomes DC.
