Thoughts on very cheap speaker cables

Hi all,

Has anyone tried speaker cables made as follows:
1. 4 single 12Ft strands of 22 AWG certified OFHC CDA
101 annealed temper copper ($0.25 a foot).
2. Each inserted in pure lowest dielectric woven cotton.
3. Each assembly inserted in lowest dielectric PTFE tubing.
4. The ends will be sealed with a PTFE sealant.
5. About 1" of bare wire will protrude from the sealed
ends, coated with a low dielectric antioxident.
This will provide a twisted pair, held together with shrink wrap, for each B&W803N speaker connected directly to an Aragon 8008bb amp. All thoughts will be greatly appreicated.

Thanks,
Henry Rancourt
