Everything depends on whether you want your cables to transfer signals with no editorializing, or: to act as a tone control.
I’ve been using both their KS-1130 and KS-1030s, in my system (on sources), over the past couple decades.
Having listened through them with my own recordings/tracks: I’m confident that they allow what’s in my music/signals to flow without compromise*
*iow: transparent
Keep in mind: cables cannot add anything to a signal. They can only block or hinder some things within a signal, which makes other aspects seem more pronounced.
