I just read the article and it refers to a coaxial cable between the SW and AV from what I understand. In my system and the ones I have built there never has been, it's just one cable with a canare connector. I have noticed a hum from my SW but only when playing Blu-rays on the PS3. The hum will go away if I turn the receiver to (Pure Audio) that's what Onkyo calls it anyway. From what I understand it turns off unnecessary "things" in the receiver. It's weird though I don't hear it through the Tivo or Apple TV only the PS3....Any ideas???
