These are terms that appear often in
high-end literature written in language that is also often technically
intimidating to audiophiles. Simply stated, skin effect is a phenomenon
where high frequencies travel along the outside diameter of the
conductor causing a timing difference (phase shift) of the travel
of high notes to low notes.
Magnetic interaction is a phenomenon that produces distortions
as a result of the crossing and intersecting of individual conductors
in a cable. Capacitance and inductance are electrical characteristics
that, if excessive, can cause filtering (reduction of volume) of
high notes and low notes respectively.
All of these effects must be considered. Many high-end cable companies
have expounded on their "unique" and "creative"
strand/construction processes and have proclaimed that only theirs
effectively cures the ills cited above. There are only five types
of strand geometry constructions: bunched, concentric, unilay, braided
(coaxial), and rope lay. All of the high-priced Cables we examined
use one of these constructions. These geometrys, as well as weaving
(cabling) patterns are all accomplished by standard strand and weaving
machines in use today by virtually all wire and cable manufacturers.
