I am going to be slightly nasty . Directional cables, North or South East or West. Directional cables tells me the cables aren't linear and are tuned to give a specific sound, Which is Ok if you like the results. Its not for me. I mean if you want to tune the sound why not use tone controls, Graphic controls, a MEN 220, a Parametric EQ or a Room EQ, or now the new mini DSP's?
