An 8ohm speaker is 6-7 ohms dc resistance. A metre of 1mm^2 cable
is 44mohm, so 2.5 metres is 0.11ohms. So no detectable difference
on the sound whatsoever.

The resistance is not what's being discussed. What's the impedance
at say 5kHz?

Impedance of the cable when being driven by a 0.1 ohm or so source?
Irrelevant.

Are you sure that the effect on the source impedance that the speaker
sees cannot be significantly affected by a comparable series
resistance? What about the story of speaker damping?

Are you talking about cable resistance or its impedance at a specific
frequency?

Obviously you use cable with a suitably low resistance to maintain that
damping factor.

The question would be can any cable likely to be used have a suitably low
resistance, but a high impedance at any frequencies within the audio
range?

This is all sounding terribly like the complaints the BBC received in the
early 80s when Radio 3 started broadcasting music from CDs. " They sound
terrible - digital does that to sound." But you haven't noticed that the
distribution to the transmitters has been digital for about 10 years."
