Good quality copper wire

Beautiful flexible copper

Unlike many speaker wires, this is pure copper and therefore very thick

It looked like pure copper (unlike CCA), but I am not 100% sure, as packaging did not have much info on it

far it seems like is pure copper because I used a knife to scrap the top layer.

This is rather stiff for pure copper and the cover is like something from Radio Shack

If you don't mind spending a little extra for pure copper then this is the way to go.

Top shelf speaker wire, heavy pure copper, heavy insulation, very happy with this wire Best of all made in the USA

Good to have solid copper strands that deliver the sound for a very reasonable price.

I was getting tired of the cheap and brittle copper-clad aluminum "CCA"speaker wires

It has significantly higher resistance than pure copper, and is quite brittle.

Speaker wire is all the same to me as long as it is pure copper

Plus they're 'Proudly made in the USA'.If you are looking for the best wires for your speakers get this brand pure copper eXtreme is the best

I would not pay for the oxygen free wire myself, as there is no measurable difference in conductivity between pure copper and the C10200 grade oxygen free used for audio.

The individual strands seemto be solid copper, not CCA.

Good quality, legit copper (no "copper plating" of aluminum)

Solid stranded copper 14 gauge speaker wire

This is nice wire, solid copper core and not the copper clad aluminum found all over Amazon and priced about the same.

These are the real deal, 100% copper.14 gauge is just the right size to fit snug into banana plugs and the pure copper locks in tight unlike the 16 gauge copper clad aluminum wires I was using before
