What's its purpose when, supposedly, only one end is grounded along with the outer shield? Might it reduce inductance or capacitance if braded with the two signal conductors?
Thanks for your input.

There is no need for a third core wire in an unbalanced interconnect that I am aware of.
Using double core screened cable, you can connect both signal and return while connecting the screen at the transmitting end only.
Even simpler, with single core screened cable you can use the centre conductor for the signal and the screen (connected at both ends) for the return.
Either way suits a short interconnect in a domestic Hi-Fi environment.

That's what I suspected. Maybe it's cheaper for AudioQuest to use the same cable for both their XLR & RCA versions.
Could you have misunderstood the AudioQuest description?
That is the same wiring as in my first description - nothing special, just common practice.

1500 UKL for a cable? I think it's a test of something unrelated to audio but if the cable were used with an unbalanced output to a balanced input the second conductor connected to ground at the output would still afford the noise reduction characteristics of a balanced line.

Galu, I wonder if my Diamondback might be different than today's cables. Mine is 20 years old and an old ad photo shows three wires. Two signal conductors with another grounded conductor (at only one end?) plus the outer braided or foil shield.
The term asymmetrical is used with their new single jacket interconnects. Apparently, there are two signal wires for each channel in a single outer jacket. I forgot if there's a common outer shield or one shield for each side. I can understand why a coax might be considered asymmetrical, but if the signal goes through two dedicated wires, with a separate outer shield, why "asymmetrical"? Again thanks.

A quick search for tha Diamondback interconnect shows you are correct in your original description regarding a third wire.
Whether this is a technical tour de force or simply audio hype, I'll leave up to you to decide! Audioquest Diamondback Stereo Interconnect available in popular lengths Hifi Gear
It's good to know my memory isn't completely shot. So, in my old style it would seem the 3rd wire has no job, but my paycheck gave it a place to live.
Tech terms seem to be used loosely, sometimes. Perhaps AQ is assigning their own meaning to: asymmetrical.

The way I read it, in the RCA configuration, they are simply paralleling two conductors for the return path and using the third conductor for the signal path. The screen is connected at one end only.
That's all very fine, but I can't see any advantage in the doubling up and AudioQuest do not attempt to explain the 'performance advantage'.
I'm happy to avoid exotic cable geometries and simply stick to what's tried and tested.
Some of those high-end cables do look awful pretty though! 😉
