Has anyone heard of Audiocadabra cables?

They are in India and offer free shipping, thanks for the replies. I'm going to try the USB as other vendors charge $$ more for silver.

106 & 107% of what?  Nonsensical marketing?

Common nomenclature is to set copper conductivity at 1.0 and compare others on this scale. Silver is the only metal more conductive than copper at 1.07. However, I do stand corrected. Looking this up I see silver listed as 1.05 to 1.07 so 1.06 is quite reasonalbe. I’ve always remembered 7%.

Other metals:

gold .70

aluminum .61

brass .28

steel .10

@carlsbad, that is an interesting factoid, thanks for posting because I had no idea what 106% meant.

Here’s an old review of one of their earlier USB cables.

                                        And, another.
