Power cable from wall socket to power strip

Hej

Firstly; yes I believe that cables makes a difference. All cables. I don’t want a discussion with ”non believers”.

I use a power strip (Wireworld Matrix 2) which is connected to the wall socket with a Furutech Empire. But now I need a little longer power cable and I thought; does the power cable from the wall socket to the power strip really matter? I mean, all the way to my wall socket it’s just ordinary wire, so why should the part to the power strip matter. It’s just the last bit to the devices that matters, I’ve been told. Or…?
What are your thoughts about this?
