RCA cable design


In a single ended cable, does the signal travel through the ground cable, or does it just dump its voltage to zero into ground? Is the quality of the conductor wire for the ground as important as the signal wire?

Come on MC, That was, "where's the BEEF"? ;-) 

The fact that there is a slight timing issue, between pos and neg. 

<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>>

In "real" cables there are slight out of phase current flow due to capacitance, induction and dissipative dielectric losses in the non-conducting materials. This will cause slight variation between the voltage at source and destination.

I find the answer interesting, not the question, I haven't quit figured that out YET.

Normally, there is a 500 word answer, I like the trimmed down version.
That explains HOW an RCA works.. Apply it where you like..

I agree it takes a neg, pos, covers, shielding (optional) and or armor.. AND yes, how it sounds. I'm just not sure that's what was asked either.

Here we go.. Ok is that the question? OP what was the question again?

Now were talking about flow? Current? but not what he ask..

He ask if two different conductors, made a difference, ground, vs signal (pos)? I say yes, it does.. Again I still like the answer jder, posted.

I say that because I've mixed and matched on speaker cables, and it made a big difference...Copper/silver ground, with copper/copper pos, and a weave..

Reverse the two, use the copper/copper on the ground and the silver/copper, for the hot. On my system the tweeters will boil your ears, and the mids sound like they are wired out of phase.

Reverse it.. Wonderful again. Actually one of the better combos I've done, for small planars, and a splash of tungsten with copper, not silver, is pretty darn cool too...

The "signal" is the voltage level versus time between the center conductor and the ground potential at the destination. In an ideal cable this potential (voltage) is the same at the source and destination.

What a great explanation.  I really don't need all the frosting a lot of folks add to the cake, so to speak. Direct question, direct answer..
I wish I could keep it as clear and concise.
Thanks.
