In Reply to: RE: DIY Auditorium 23 speaker cables posted by pictureguy on June 27, 2019 at 19:51:37
Well, I'm not sure that there are electrical features of that speaker cable that aren't wholly encompassed/expressed in its physical features. If I can get the same plugs, the same wire properties (metal, construction, size, dielectric), the same twist ratio, and the same soldering properties (probably impossible), what else is there?
I'm sure the only candidates are copper, silver-coated, and silver. I include copper, because the photos I saw may not be trustworthy. I am inclined to try copper first, despite the photos, because 1) Art Dudley was convinced of that, and 2) I heard my system on both copper and silver-coated copper Wireworld Eclipse 7 cables, at my dealer's, and the silver-coated cable sounded harsh immediately, obviously. It was night and day. However, if I like what I hear, I think I would be willing to make a second set out of silver or silver-coated copper, just to tinker.
May the bridges we burn light our way....
Follow Ups:
Looks to be silver coated copper and it may be a custom wire. Bite a bullet and buy a used wire. You will loose weeks on researching and couple of days on construction instead of paying $500 which after you're done with honeymoon period you will get back in it's entirety while your DIY effort will be wort $10.

The twists are there because the owner of the cable cut it from the longer run and was selling the excess wire. Aud 23 is too cheap to be a full silver wire. There is a recent mania of old WE style tinned copper but 23 is too old and being a German cable it's likely a silver platted copper. The best way to get close is to buy a piece of original cable check if you can get close with DIY and if yes sell the cable and make a copy.If not sell the cable and find something else which you like or bite the bullet. Break-in is important and quality of soldering as well.
That's the photo! I don't discern silver-plated copper in the photo. I also wonder if the silver visible in the photo is actually solder "tinning" on the wires, but there doesn't seem to be any reliable signs of tinning.
After a brief search, I couldn't find any used cables for sale. Also, I need a fairly long cable (15 feet?), and I doubt my chances of finding that length used.
My eyes tell me that's an all-silver cable....
One problem with the photo is that it shows twists on the pairs going all the way to where the plugs were. As I recall, all other photos of the cable show no twisting between the banana plug and the shrink tubing. Hmmmm....

I'm the wrong guy to ask. Especially without a sample of the 'target' wire to measure and inspect.
The big proviso in your answer is IF. IF you can duplicate a bunch of stuff about the wire, connectors, fabrication, you should get REAL close.
It is possible that the OEM of the 'target' cable either uses Off The Shelf stuff or if the order is large enough, can have something custom made. THAN you're in trouble!
If I were making a DIY interconnect? I'd investigate single crystal copper. And than see how it can be purchased, with what insulation and sizes.
Speaker cable? Up for grabs, as to what you can get and at what cost.
Too much is never enough
That is a big IF. But I think you're right: I should be able to get close.
It's funny, because I saw here that a previous user of the cable thought it was made from Belden wire, and I thought to myself, "if that's true, and Belden doesn't have OCC wire options, I will probably go with the OCC from another manufacturer." This project is stirring up my audiophilia nervosa....

And IF you can match a target wire or cable Electrically, no guarantee of identical sound. Insulator type? Wire composition? Connector and attachment?
And depending on YOUR choices and what's available VS the OEM, your version may be better, or not!
And more or less cost effective. As if the highest end of cable purchasers don't have their OWN version of 'cost effective'.....
Part of the REAL hangup is you'll never KNOW. Every cable maker has an opinion. and I susepct each makes does something really well and some other stuff...not so smart.
Check the Beldin Catelogue for something of interest and perhaps order up some samples...enough to build a pair for test.
