Shielding isn't actually effective at blocking all frequencies anyway. If you are really concerned about high frequency noise, a combination of braiding and sheilding probably the way to go.
The theory is that the cables that are unsheilded sound better because they allow the signal to generate a fuller magnetic field around (outside of) the cable. The sheilding can retard the fields of the actual signal, just like it does for external noise.
I use sheilded cables for digital and video. Unsheilded for audio.
