How does someone "put a signature" on cable ?

True story - I once lent someone my old Hifi. Since this guy had a habit of
keeping things for a little longer than he should I put my name on the
whole lot, cables included.

Judicious adjustment of the bass and treble controls for one.

This made me think. Steve - Do you think magic cable can do anything to the
sound an EQ can't? Most of what you've said so far seems to be around
boosting/limiting certain frequencies.

Hmm...
silly looking cable £150
twisting bass knob free!

There is a cable - OpusMM - that actually HAS a large crossover network
built in along it's length.
