Your favorite OCC speaker cable

Thanks for the suggestions. The Fidelium cables seem interesting. The language on the website doesn’t tell me much about their invented alloy, but I suppose hearing is believing. I know OCC has worked well for many people and the list of companies using is it impressive, too. The idea of finding it bulk seems like a good way to go, though I am not sure my DIY efforts would be as good as a cable I’d buy! 

@teo_audio.   
Thank you for those links! So, basically, a $10.00 roll of the wire, which is 30’ long, will provide enough wire to make a single 8’ braided 6 lead wire. Two rolls, two 8’ runs, get some heat shrink, some sleeving, a bunch of audio note banana connectors and you should have a very nice pair of cables for very little money. 
Certainly a worthwhile and inexpensive experiment. 

cut the outer skins off and use the inner insulated conductors only. one step better again...
There is a neg and pos run for each foot of it. all packed in an outer skin. cut that outer skin off...
or, to say it differently, for clarity...with the single 30 foot roll, you actually have 60 ft of a single conductor. 30ft of red colored insulated wire --  and 30 ft of black colored insulated wire

Wireworld Eclipse has several models ,and patentedlowest dielectric and ,very important No brass connectors like most ,Silver over Solid Copper .

@teo_audio - Can you share what Belkin means when they advertise "hybrid-conductor technology"? What is hybrid? Are there a mixture of OCC and OFC wires, a mix of stranded and solid core wire, is the wire tinned or silver plated, is the negative wire a different material or different size, or is "hybrid" something else altogether. Also, can you share whether the PE insulation is foamed or not? I could not find answers to these questions in their product literature. Thanks.
