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

@jumia 

But I see higher end RCA cables with two conductors and ground wire. Which is better?

How would one know?  Wouldn’t one have to try both first before answering this question?  If two conductors happens to sound better, wouldn’t every cable manufacturer use this configuration?  What brand of higher end RCA cables are made with 2 conductors and a ground? So many questions…

hey so don’t get all philosophical on us now!!... 😂

Interconnects can be a very important components in a system. The better the boxes in your system the more important the interconnects are. With cheap interconnects the actually materials are important and maybe the configuration. But as the cost goes up… as does the effort in getting better sound the less the specific materials and configurations determine the output. It is the effort put in to choosing materials and configuration. There are lots of ways to accomplish great sounding interconnects.

In most cases one parameter will not determine the sound. It will be highly dependent on your system and the specific interconnects.

Got no audible difference between using two rca cables vs a single Coax

I prefer coax less cables
