Jon, in the past I have observed that RCA type (audio) cable may not have 
complete shielding; some ever have had a small thread of wires and called it 
shielded.

You might try coaxial cable.

  Hi all,

  I did replace my cable the other day from Cat-5 shielded cable to a RCA
  cable that is also shielded. But with the Cat-5 cable I did not get
  electronic noise. But with the RCA cable I do. I rather do not want to
  switch back to the Cat-5 cable, as it is harder to manage.

  What might be the reason why I am seeing electronic noise on the RCA
  cable ?
