Anyone who tries soldering enamelled wire without first removing the
enamel by other means is a complete pratt. Probably the same type who
would use - or even try such cable for LS use.

But I use enameled wire for winding chokes, and transformers.
The cheap **** from China can be tinned by just persisting with a
soldering iron and flux core,
and its only thin polyurethane enamel. Its softer than the the brown and
green stuff made
with enamel of polyester-imide which you can't tin with a soldering
iron.

Phil loves to say I am complete ********, as we all know, but
using enamel wire for LS cables needs careful thought.

McIntosh used triple insulated enamel wire in bifilar windings for OPT
in tube amps where the two windings wound side by side had a 470Vdc
potential difference.
They lasted OK, so an LS cable should because of low voltages, but then
unlike the varnished wires in an OPT,
the LS wire strands are subject to movement and possible shorts.

Pppl used to plat their own litz wire to make a cable. This avoided skin
effect, and
would keep RF wire resistance low.
Then they'd say it sounded better.

Somehow I think such betterment claims are bollockesque in nature.
