What speaker cable made a major difference in the sound quality of your speakers??

An 8’ long DIY stack of 3/8" wide .999 silver foil, each foil wrapped in Teflon tape, stacked, and drawn through an earth-grounded shield of tinned copper-braided tubing. About 1.5 lbs. of silver in all, at the commodity price of $750 plus a long afternoon of work.

@dgarretson .. what is the braided copper for? Is that one of your conductors​? Or are you dividing the ribbons into the pos and neg conductors and using the braided copper as a shield?

The latter: as a shield floated from the conductors. I soldered a wire to the braided copper sleeve and connected that wire to the ground pin in an AC outlet. Each conductor is in a separate sleeve.  Shielding improved upon the earlier unshielded version.

@toddverrone .. the whole project didn’t take much time at all. I used 16 gauge wire and 14 gauge jacketing. The wire threaded easily enough and just needed to be guided deliberately. Here’s a link to my blog post about the build where you’ll find a couple of links to exactly what & where I purchased the materials I used:

Aauugh, I just had to read this thread. I have a pair of Morrow SP-7's on the way and now I read all these glowing reviews of the Clear Day's. I moved up to the 7's from the 5's on a trade-up deal. I think I'll let the Morrow's burn in good then pick up a pair of Clear Day's and sell which ever I don't like. The good thing about cables in this price range is that it's actually affordable to try different brands. Anyone care to comment on the SP-7's?
