Discovery Cable Signature

This listing is for a pair of Discovery Signature interconnects.  They are exactly 42" in length.  They have locking plug sleeves.  Moving the sleeve to and fro to adjust and tighten the plug connection.  Discovery has 4 types of interconnects, these are somewhere in the middle, they sound excellent.  Discovery uses pure high grade copper and excellent plugs.  I'm not sure of the purity of the copper but it up there around 99.99%.  They used copper from the  mine in Butte Montana, which at the time had among the purist copper in the world because of the Anaconda Smelting process', The copper ore was taken to.  I have a lot of Discover Plus Four cables which sound as good as the Signature and discovery's top of the line Essence which I also have.  Using this cable on your system you should see an improvement in its sound.   I'm shipping it in a 14" x 14" x 3" box with bubble wrap insulation.
