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

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.

I've heard inexpensive star quad from Straightwire that Excell. 

So how does the RCA connector accommodate 2 connectors(positive and negative) and a ground wire.

@jumia Simply by careful soldering.

^Twist them together.^

I put together some XLR to RCA yesterday.

On the Neutrik XLR:

• The two clear wires twisted together to pin 2.
• The two blue wires twisted together to pin 3.
• The shield all twisted up and soldered to pin 1. 

On the RCA:

• Clear wire pair twisted (XLR pin 2) to RCA center
• Blue wire pair twisted (XLR pin 3) to RCA shell.
• shield trimmed back, and not touching the shell at the RCA.

On the DAC I split the power and shoved a ferrite core on, with the +V in the one direction and the -V wound the other way.

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
