What's better, one conductor or two conductors for an RCA interconnect?

To clarify, I understand that there is one conductor, generally copper, and a shield which I guess also is considered a conductor. And then there are cables with 2 conductors, each a separate strand separately shielded. And then a third wire of sorts that acts as a drain or a ground.

Is it better to have two separately shielded wires, which I guess can have multiple strands twisted around each other, versus a Single separately shielded copper wire?
 

Higher extremely expensive analog interconnects have two conductors Plus a separate wire serving as a ground.  If it don't matter for rca Cable purposes, ie. Unbalanced, why is it done. Presumably because it increases quality, and if so, why?

So what happens if you Connect the ground to the connectors on both sides of the RCA cable? If one side of the ground is not connected to the other side within the cable wouldn't the impact of a ground wire only connected on one side become an antenna?

Isn't it Better to let the ground flow back into the component and let that take care getting rid of the ground activity.

Is it better to connect the ground to each side of the RCA cable?

So it appears there are no clear Views on whether the ground wire should be connected to each RCA connector.  So you have 2 connectors connected to the RCA connects ans a ground wire connected to both RCA connects.  
 

So it is on this very point there is no clear rationale or consensus as to how the ground wire should be handled.

Personally I think this is really sad and should really frustrate those trying to choose the best interconnect.

But if you leave the ground on one side unconnected wouldn't that risk creating a noise problem because the unconnected wire within the interconnect rca cable becomes an antenna??? Where noise has nowhere to go except to negatively impact the two connectors?

So I’ve inquired about one conductor versus 2 conductor as part of an RCA interconnect. There has been a substantial response from very very smart people.

Unfortunately, somehow the brilliance is having trouble leading to a point where someone can understand what is being said. brilliant people herein don’t really do a very good job explaining things Beyond extremely technical jargon.

This thread of information is a testament to how challenging it is for brilliant minds to communicate in a manner that can be understood by us average mortals. Truth be told this discourages people and is an unattractive aspect of this hobby of sorts.

Do these really brilliant people know that most people reading the comments have no idea what they’re talking about. It’s really really hard to understand.

I have always considered True genius to be the ability to explain a very complicated situation to the masses. Otherwise what’s the point.

Recent answers Have been amazing.

The RCA connector - isn't it designed to accommodate one conductor and then gripping the shield where it is soldered at the base of the connector.  So how does the RCA connector accommodate 2 connectors(positive and negative) and a ground wire.

I really like atmaspere’s answer including discussion about the shield carrying the signal. It made a lot of sense to my simple mind.

I like Mogami too. I have their 3173 Cable as a interconnect between amplifier and preamp. This is a little thicker than the 2549 and also has a drain wire Plus 2 conductors. In this situation the drain wire is connected to both sides.

Still breaking in and thus far it’s a wonderful cable and very inexpensive.

Finally I appreciate the help. OK so you combine the two connectors before attaching to the RCA. Makes sense and I guess you have to mix them together.

At least the two conductors had a peaceful journey from the preamp and then all hell broke loose when they reach the RCA connector.

Blue , I believe is the ground connected to the Shell on both sides of Cable as mine have been done and recommended this way.

And the shield is out of the picture by stripping it back

Not sure why the hell every comment above made this issue so damn complicated

Great job holmz
