I remember reading somewhere on this board (from one of Teddy's posts maybe) that the Schoeps active cable is reinforced with kevlar strands.

here is a lot of nonsense about cables. Cables have no mystic secrets
- it is pure physics.
As even for hard core purists the audio frequency range ends somewhere
below 50kHz (I would be glad if I could hear 20kHz ..), we are far away
from real high frequency where special characteristics like skin effect
etc. have an influence. So we can simply watch resistance, voltage and
current.
Silver may be a better conductor than copper but it is very affected by
corrosion. Also a pure silver wire will break when you bend it. On the
other side the difference will result in some milli-ohm. The
microphones have output impedances of some ten ohm. So you may choose copper or
silver or gold - you will get no audible difference. Other electrical
and mechanical properties are much more important.
We use a very special copper alloy reinforced with Kevlar fabers. It is
made for SCHOEPS only and offers mechanical advantages (elasticity at
cold temperatures, high tensile strength and no twisting when you hang
your microphone and the room gets warm)
