If your system is all the same manufacture then I could see maybe use one cable manufacture, but I suspect most people have a mix of component manufactures and speakers. I use two different brands for the most part and am very happy with the mix.
I use WyWires IC and PC on my analog side along with speakers and use Nordost on my digital components... just pulled out a Clear Day balanced from preamp to amp with a Nordost I just picked up. I have several Clear Day Cables IC and SC and Kimber Kables PC which I’ve slowly pulled out of my system which I’ll keep for a second system... maybe.
As mentioned by others, cables are subject to personal taste. There’s no right or wrong; just what sounds right to you. I will add it might be easier to start with one brand but it’s just a start.
