Looking for Solid Core Speaker cables

There is a person selling a 10 foot pair of Audioquest Indigo speaker cables with spades at both ends.  They are solid core wires.   I owned a 20 foot pair years ago and I am sorry I sold them.  

Every AudioQuest cable is solid core except their glorified zip cord X2 and custom installation FLEX/Slip series. 

Look @ Neotech bulk wire.

I’ve linked solid core copper/Teflon.

They also have solid core silver/Teflon.

I've read about a rectangular solid core wire they make, but don't know where to source it.

I used to use these with my Martin-Logan CLSs and they were great.  I told HP about them and so The Absolute Sound did a review of them, which was quite favorable.  They are solid copper (or silver) ribbons.  Weren't very expensive, for the copper, back then.  They have fallen off the map somewhat, but maybe you  can contact them and see what you think.

I have been using Clear Day Double Shotgun solid silver speaker cables for years now. They are no longer made, however show up used from time to time.
