Just for interest,
I found a difference with types of copper in an amplifier I prefer solid core copper as used in electrical wire. (on power output)
The next that gave a change was linear crystal oxygen free which seemed to not be as warm sounding.
The Oxygen free seemed to give preference to mid frequencies, this could just be the make of wire or insulation material.

Now there is also the problem of connecting the wire to terminals, this is a bit of a mares nest because the load is just low ohms and the wire may be an ohm or more then there is the junctions at either end. However if looking at this you have to ask about internal wire and connections particularly with tube output transformers which have a coil on the output of copper wire.
The size of wire inside equipment has an effect on bass response due to transient current, so what effect does wire type have?
Interestingly I have had good results using magnet wire with insulation as used in coils inside speakers.
Just a personal belief that the conformal coating stopping oxidisation of the surface seems to have an effect.
So what about silver plated or gold plated
its a bit of a mine field. I have three speaker wires I can try on my system and they all "seem" to sound different. However there are to many variables, insulation type, cross section, and conductor type.
If its possible to hear inductance then your stuffed (I believe you can) but each to their own.
I know that national grid have major problems with losses and inductance at 50Hz, OK that is over miles of cable.
If I can hear the change of a non inductive resistor vs inductive with a few turns of resistance wire where does that leave anything else. If you believe changing component types in a crossover has an effect then what's the effect caused by?(at low ohms)
A dumb moment:
If a speaker is a coil of wire on a magnetic material, that's a choke isn't it?
