Re: [ARSCLIST] Compression (was Re: [ARSCLIST] A fundamental Flaw ...)
Actually, fusing can colour the sound slightly. The fuse is more than just
a conductor. Since it is designed to melt at it's maximum rating, and on
loud passages, that maximum rating is theoretically approached, the
temperature of the fuse element will vary (taking into account its thermal
lag) with the envelope of the signal.
Since the resistance of most metals goes up as they are heated, this
becomes a variable resistor that is program dependent in series with the
speaker. To some small extent, this would compress the signal coming out of
the speaker. As the signal got louder (overall) the temperature and
resistance of the fuse would go up and looking at the fuse and the speaker
as a voltage divider, the percentage of the signal at the speaker terminals
would go down.
Now this may not be a significant effect, but there is reason to believe
that there is some effect. I think this effect would be far more measurable
than some of the other items touted by purist cable companies, for example.

Since a fuse is only a section of a conductor which will carry only
the stated amount of current before melting, any effect should not
only be minimal...it would be less than the inductance created by
not running speaker cables in an absolutely straight line from the
amplifier output to the speaker locations!
