If a speaker cable added 1 - 2 ohms of resistance would that be?

I've concluded audiophiles are crazy. You can sell them anything if you make it expensive enough and get some guy with no qualifications to say on YouTube that he likes it. Then people will like the sound on one album and one system and say it blows everything else away. Eventually a wacky "theory" {completely unsupported by meaningful data or known theory of electronics) will appear to explain why it's better. After a while, the owners will sell it and move on to something else.

Sorry, I must have indigestion tonight.

If the speaker’s impedance changes markedly with frequency -- as speakers tend to do -- a couple of ohms in the speaker cable would be a bad thing indeed. It would form a voltage divider whose values vary with frequency. That would change the frequency response in what you hear from the speakers. (I mean it would change it objectively, not in some magic audiophile way.)

Of course, @crustycoot is correct that a couple of ohms of speaker-cable resistance will degrade the realized damping factor considerably. The nominal damping factor is usually computed

DF = 8 / Z

where 8 is the assumed impedance of the loudspeaker, and Z the output impedance of the amplifier.

So you would achieve a nominal damping factor of 200 (not out of the ballpark for a SS amp) with the output impedance of the amp being 0.04 ohms. If you add 10 feet of Belden 5T00UP, you’d add another 0.01 ohms, and the effective DF would be 160. If you added 2 ohms of cable resistance, the effective DF would be about 4.

Some prefer an underdamped sound.

P.S. I am prone to typos and simple math errors, so if I’ve made any, please point them out and correct them.
