Hey Zephyr24069,
Take a look at my review here on the GON on the Stealth Varidig Sextet for details why I have not yet found a better sounding digital cable for my system. Of the cables that you mentioned, I have heard all of them except the PAD and still found the Sextet to out perform them. I'm still kinda amazed why people love the Kubala wires so much, I find them euphonic, not accurate in my experience.
