Buying used old cables


Is there a life-expectancy of old cables? Old cables
can oxidize (rust) and get brittle. Thus, lose their
conductivity. I have old Monster speaker cable in my
storage area which shows darkened, discolored wire. Is
it still useful? Mobility, relocating, moving, bending,
manipulating, as well as aging must have negative
consequences on any cable. Should we consider this in
our purchase of "used" cable thinking we are getting a
good deal?

I must admit that serving the compulsion to shorten all
interconnects, speaker wire and power cords to the short-
est length, I have replaced male ends on power cords with
hospital-grade connectors while cutting off significant
extra length of wire. That suspends the wire off the rug
as well. I have even soldered new RCA connectors on some
interconnects. Sonics have not suffered noticably. Now
I would not do this to an expensive item that comes with a
swedged-on connector. The orderly snake-pit behind my
equipment sure makes me proud, neatnik that I am. But,
I don't know how equipment mfgs. look on this practice and
I certainly don't know what damage I am encouraging. It
may just be a trade-off, though; short connections for
shorter longevity. BG
I've had the copper strands inside Monster cable turn green after having it for a year or so; probably caused by oxidation.

Wow, that's still going on. They had that problem decades ago when they first came out. That's not a good sign.

What metal besides gold can withstand the corrosive
damage of Oxygen? We are at the mercy of a giant
presence that invades and permiates most protective
shields at various but persistent rates.
Conclusion: Used, flexible wire is suspect and should
be looked on with caution and only as a temporary
addition to our systems until we can go with replace-
ments of new wire. Even these should be given a
proposed time of replacement. Maybe we should even
ask for an imprinted date of production stamp so we
can refer to that time and plan ahead for replacement.
The value would diminish as time passed on the used
wire market.
oxidation without representation is tyranny.

cross at the green, not inbetween.
