Mark,

Is this the wire you are using? http://www.mouser.com/ds/2/14/1805%20GR005-212239.pdf
If not how about a link for reference.

That seems to be right, the link you sent. Is that wire silver plated?

Could the procedure described in http://www.diyaudioprojects.com/Power/DIY-Shielded-RCA-Interconnect-Cables/
be used to make a stereo jack - 2 RCA male cable of 5m long of the following components:

Hi Guys, I on the other hand only use stranded wire for interconnects. Belden 8412 for interconnects with Switchcraft gold/nickel terminations. I got put on to these via some really serious Japanese Audiophiles. Internal connections with Mogami 2333. The later is nice to work with as it is small diameter and spiral copper shielded. The 8412 is instrument wire and with its cloth/fiber liner can be difficult to use, but IMO worth it. I'm sure the solid wires work fine, but so do these and I am extremely picky on sound (and low noise).

Good listening
Bruce

I've got some Mogami 2534 cable that i would like to make up some RCA interconnect cables with.
I was told that wiring the two white wire for the conductor and the two blue with the shield as ground on one end.
The other end would wire up the same except no connection for the shield.
Or can i just wire up both ends the same as the first end i mention, i was told this may introduce noise in the signal.
Do you have some guidance on this for me Bruce.

Thanks for your help
Carlos

Hi, I do that with some of the Mogami cables that are really long. They work quite well. There is discussion as to which end the one with the shield connection should go to. I have tried both ways and generally seem to get better results if it is on the far end (at the preamp, etc) and not at the signal entry end. Then too most of my gear runs a separate ground wire between all the chassis except the power amps.

Good listening
Bruce

Thanks for clearing the air Bruce. You mentioned you've done the on off shield connection on long runs,
what about short runs like 2 feet, what would work best, both shields on end on or one on one off?
I have a lot of these to make up and i wanna get it right.
By the way! would it matter between the blue and white wires which one i should use for hot or cold or it don't matter?

Thanks for your help
Carlos

Hi, Never connect the shields on both ends if one of the conductors inside is the signal ground. It is a wonderful way to make a ground loop. The color of the wire used for hot and ground doesn't matter. The shield end seems to work best on the non-source end all the time in my system. But as most folks know I am fanatical about hum and noise and while I can hear and sometimes measure it the difference might not be obvious to many folks. I can put up with a very low level of tube hiss (about at -90dbv) but no hum.

Good listening
Bruce

That was a speedy reply! That also means my cables will be directional as well. I feel so confident now with that part of my project now.
Now i can also work on my speaker project as well.

Thanks for your help
