I recently bought some Cat 6 cables as my understanding is that
they've got more shielding.
CAT5, CAT6, and all variations thereof consists of four very good
twisted pairs, each twisted at a different rate to minimize crosstalk
from one pair to another. It is NOT shielded.
Twisted pair cable, in general, is excellent in minimizing the pickup of
all forms of noise, whether it be hum, buzz, or RFI. It is equally
effective in reducing the radiation of noise from that wiring.
If you have any problems with RFI or noise involving telephone wiring,
or loudspeaker wiring, the FIRST thing I would do is to make sure that
all wiring is twisted pair. CAT5/6/7 is far too small for loudspeaker
wiring, but it is excellent for telephone lines, including those
carrying any form of DSL.
