Hey there, i have a question regarding different wire types used in one cable.

I have seen some 8-Strand cables using 4x pure copper and 4x silver plated copper wires.
Each pin (L+/- and R+/-) is connected with one pure copper and one silver plated copper wire.

What is the benefit/purpose behind this?
All i can imagine is the looks of it, having two different colors braided together...

In terms of basic electronic knowledge, using different wires in parallel is a big no.

Thanks for the answer.
 
Maybe i did not understand this correct, and they use (for example) 2xpure copper for L and R+ and 2x silver plated for  L and R-, but i don´t see any reason behind this...
 
Any idea how someone would use a cable like this?

Or like this:

It just puzzles me...

Hi all,
I need to make up a 5-pin DIN to 3.5"mm cable, but having a bit of trouble selecting the right connectors.
It's to connect a raspberry pi (old model) to an old amp that is used for a PA system. Here's a picture of the female DIN connector on the amp:

I'm not sure of the markings on it, and I'm finding conflicting information online - either I need to wire tip to pin 5, and sleeve to pin 3, or I need to wire tip to pin 5, ring to pin 3, and sleeve to pin 2.
 
I was looking at DIN connectors like this: http://ie.rs-online.com/web/p/din-connectors/0491011/ but what does the following comment in the description mean: "Mate with the cable mount sockets of same configuration only." Is that relevant?
 
This is the 3.5mm connector I was looking at: http://ie.rs-online.com/web/p/jack-trs-connectors/3951131/
 
This is for a PA system in a factory, so sound quality isn't exactly top of the list, making it work is pretty much about all that matters. I understand the old PI doesn't drive much, but I'm assuming it'll be enough for the amp, if not there's plenty of USB converters or HiFi-Pi boards I can use, I'll still need a working cable though.

Polarization? Silver for Left, Copper for Right?
Or Silver for +, Copper for -?
Looks?
Schiits?

i've already test some cables combination (silver coated copper with pure copper). and for vocal i think best combination is pure copper for signal, silver coated for ground. And for detail and musical characteristics, i prefer silver coated for signal, and pure copper for ground. 
second combination also gave wider soundstage i think.

The sennheiser HD598 and momentum 2.0 use the same locking connector right? Anyone know of a US seller for the connector?


It looks like it might be.

I secured my connectors from Ted at TheHeadphoneLounge.com. Just email him and tell him what you're looking for. Explain that it needs to have that latching design. He should know exactly what you need, since he worked with me for a few weeks until we found the right connector for my Momentum cable.

Thanks for your answer, very interesting.
From what i understand i guess you are referring to a single ended design, using (for example) one pure copper wire for L and R and 2 plated silver for the combined ground, right?
I think in a balanced setup this can't be applied in the same way, or am i missing something?

You're the best PinkPowers!!!
 
I will contact him soon. What is the diameter of the wire you used? Nice looking cable there!

Sorry, I'm new around here, should I start a separate thread for this?
