For my set-up and requirement for my expressive guitars to shine thru, I really need Van den Hul and Two Rock. Anything lower for me just depresses my sound into the realm of mush and lack of character. I see myself heading upward for cables because they do have an effect on guitar response. If you cannot hear than happening much, stay happy and forget about cables. Sometimes its better not to know what you are missing than having to realize you can't go back to your previous sound because you cannot stand it anymore.
