Are cables really worth their high price because of their geometry?

@b4icu

So the difference in resistance, if I read you correctly, in any speaker cable is the ONLY determinant of its sound quality. 
Of course we are not in need to look further into the damping factor, as always the same power amp and also speaker/x-over is used. Right? 🤔

So in this my mentioned case, the cable with the second lowest resistance sounds the worst, the silber litz with 0.2 ohm. 

The copper braid in cotton bedded, the second 'worst' has 0.1 ohm resistance (as allways one only conductor). 

And the best sounding cable, the StraightWire has at 0.3 ohm the highest resistance. 

The DF of the Pass X350.5 is about 700,
and the 3 way Burmester 961 has a linkwitz type x-over... but none of that playes into your equation. If I got your right. 

Something does not mesh with my present learning, looking at your very simplistic argument. At all! 

So, we're either not sharing the same hearing, or some other unknown influence is at work. 

Differences of ~100 milli-ohms at such a high damping factor, being the cause of such noticeable SQ differences, really? 

So, me too, let's agree to disagree 👍✔️

if you under the geometry patents, please elaborate.  If not, waste your money on hokum. 

Twisted cables tend to have higher capacitance but lower inductance on average. It's a trade off so there is no perfect solution.  

This isn't relevant to speaker wire used at home. The main thing is resistance as long as that's kept to less than 5% of a speakers impedance we're good. The capacitance and inductance of the wire is insignificant relative to the capacitance and inductance of the speaker.

There's a whole Facebook group, called "Audio BS", devoted to hating exotic speaker cables.   There's good reason.   

About 10 years ago a buddy of mine was landlord to a hi-end audio distributor.   One night, he went into their space, disconnected their hi-end audio speaker cables, and wired up 24 gauge zip cord.  What Radio Shack used to call "speaker wire" back some 40 years ago.   He did this in such a way that it wasn't visually obvious.  You had to look for it.

The next day he was chatting with the guys who ran the shop and they were gushing forth about how wonderful their rig sounded that day.  He left it there for a week before going back in again in the dead of night and putting things back.

Save your money.

There are plenty of great bargains in speaker cables.....you don’t have to spend thousands of dollars to get a good sound. My high end speaker cables (OCC copper) cost was $368 for 10FT.
