...everything has an effect, from the source,
be it mains or music format.
I would agree that the idea of trying to basically correct with wire is fundamentally incorrect as a purist approach to true high fidelity reproduction but, to dismiss its tonal effect or the contribution to synergy of the kit by its connections is equally misguided in my humble opinion.
Wire is a component. I've heard it make or break a HiFi.
So with that said, how does one create a system void of the cable loom???
It is a question as easily answered as, what is the sound of one hand clapping?
Happy Listening!
