Hi I though it would be an interesting thread to start.

Burn in of speaker cables, how long for what dielectric. What's your
experiences?

Bare OFC 5N + PVC +48hrs
Bare OFC 4N + PE about 1 hour
ive not tried Silver+ Teflon yet (need an overdraft 1st)

I have heard half convincing arguments for speaker burn in, i.e. the
suspension becomes more flexible with use I reply how does the
manufacturer
guarantee the final result. But I can see now way that the performance
of
any form of wire will change with normal use.

I do not see it.

I´m certain that these experiences are not in any kind related to the
cable.
Instead, it's the speaker that changes its resonance frequency, "Fs", to
the
specified (lower) value. Just as you first said, John. Quite audiable on a
new speaker setup. The difference is first noticed in the bass. After
measurements a friend of mine did a couple of years ago, on a common 12"
driver, there was a change from Fs=33 Hz (brand new) to Fs=26Hz (as
specified in datasheet), after a night's playing.

OK, but my main cause for concern is that can a manufacturer guarantee the
final parameters of a driver after this burn in
was the post burn in parameter measured immediately after the burn in period
when the driver may still have been warm or had the driver been left fore
several hours to cool down.
