These are the best bargains in quality speaker cables I've ever heard. The conductors are OFC and 5N PC-OCC copper treated with a colloidal suspension of gold and silver particles in oil. Detailed, open, uncolored yet very smooth. Better than many much more expensive cables I've used.
These were made up by me from a kit, which cost $200. I added a Teflex jacket and heat shrink tubing to finish them. They are 5 ft. long, bananas on both ends.

Great sound, very low price!
Thanks for having a look.
