I'm glad you're happy. As others have pointed out, there is no assurance that comparing a hand or custom made wire with odd characteristics to a reasonable speaker wire will result in no audible difference.

I had an experience where I convinced myself a tweak was improving the sound when, as I later discovered, it wasn't changing anything. A great lesson in human perception.

Since that day, if you can't show me signifcant difference in an double blind test (ABX is great) or on an instrument it doesn't exist IMO.

As always, YMMV, and have fun.

Wanna try a nifty experiment? Hang the probes of an o-scope off the amp (channel a) and speaker (channel b) ends of some 12 gauge zip cord and play music. Set the channels to subtract.
