I think it matters and again it will depend on the equipment you are connecting.
Higher quality gear will benefit more with a higher quality speaker cable or inter connect. If you are at the lower end of the spectrum then use a lower end cable/wire.
I have a modest system with all Simaudio components and Sonus faber Olympica Nova III and use Transparent Audio Wave cables and it sounds great.
Use what you like and spend what you like. If you are happy then good for you.
