The difference between Balanced Mic Cables and Aud

What really is the structural difference between Balanced Mic Cables and Balanced Audio Interconnect Cables? Sheilding? Wire Thickness?
Don't know of any. Maybe somebody else does.
Can't offer an answer to your question except to say that I have compared mic cables to other balanced cables (Mit, Homegrown Audio, Coincident, and Transparent) and have much prefered the sound of each of these I have listed.
The difference is really simple.

Mic cables are intended to serve a specific function as
a mic cable. They first have to be flexible and dependable,
and then they have to be shielded.

Since "studio" gear works with a nominal 600ohm impedance,
the capacitance of the cable is *less* important than it
might be in an audiophile application. So, this parameter
is in general not of prime consideration in the manufacture
of a mic cable.

It is more important in audiophile cables, since there is no
guarantee that there will be a low Z driver or load in the
system the cable is used with.

Also, the physical construction is often different for audiophile cables, as extreme ruggedness and flexibility is
not a prime concern.

The balanced cables I make are reasonably flexible, and have
pure silver conductors and a unique geometry, but I wouldn't
suggest using them on stage in a night club - I would suggest using
them in a studio situation for a high end recording however!

Having said that, some studios are now using some audiophile
gear and balanced cables.
