Why high-end cable manufacturers don't post measurements?


I'd like to get your take on why high-end manufacturers don't post measurements? would you like to see how a cable measure before ....does it matter to you?

Purist does post some measurements - resistance and capacitance, although not inductance.  I think they also make some excellent cables.

Do they still put batteries in cable?
That was an Audioquest thing and they are apparently still doing it.  A description and link to a white paper follow.  Believing is up to you.
DIELECTRIC-BIAS SYSTEM WITH RADIO FREQUENCY TRAP
All insulation between two or more conductors is also a dielectric whose properties will affect the integrity of the signal. When the dielectric is unbiased, dielectric-involvement (absorption and non-linear release of energy) causes different amounts of time delay (phase shift) for different frequencies and energy levels, which is a real problem for very time-sensitive multi-octave audio. The inclusion of an RF Trap (developed for AudioQuest’s Niagara Series of power products), ensures that radio-frequency noise will not be induced into the signal conductors from the DBS field elements.

System dependent so try before you commit!  Start low and move up slowly till desired result achieved.

Cost has ZERO correlation to sonic quality as RESULTS ARE DEPENDENT ON THE REST OF THE SYSTEM!

Why bother with tiny batteries attached to tiny cables when you can just get battery cables instead?
