Why not use a piece of silver wire instead of a jumper cable?

Yes I have, now reverse the direction on your jumper and see if it sounds better one way than the other. Then dip the ends in a contact enhancer. Take the same wire strip the insulation and put it in an oversize silicone air tube. You have a direction, you have the best insulator you have the best contact surface. I think you are up to 10.00 usd. NOW let it settle. :-)

There are ways to make it sound even better.. Strip a piece of OCC and do the same thing.. Use Solid core vs stranded vs large strand or small strand. They ALL sound different in an air tube and one direction vs the other.. Do one speaker at a time. I always start on the left and work clockwise if there is more than 2 speakers.

Teflon is good, BUT try air. Take a piece of # 22 OCC copper and rap that piece of pure silver about 1 turn per inch. Tuck it in the air tube. Tin the end with 4% silver solder and silicone the tube closed. Dip the ends in graphene dust and install in a 5 way binding post or add pure copper or silcer coated copper terminal ends and cold weld them (pressure) or screws, NO solder only to tin the ends. When you cench the screws they should pierce the tinning. If you use pressure, just use contact enhancer. before you compress the terminal end/wire with the dye.

Merry Christmas..

I've found that silicone makes the sound top heavy.

So Dolly Vs Ja Lo. Top or bottom heavy. Both amazing, what can I say I'm a pig and proud of it..

OK Silk or Texas cotton tube and don't seal the tube. Better yet leave it in open air and tell the grandkids to put their tongue on red one. Then turn the volume UP. Little turds.. LOL Get a randon neighbor kid conning the wife out of homemade cookies everynow and them.. Go fix that wire kid.. I always make sure there is water on the floor and the video is runnin', when I pull that one..

Merry Christmas or Gift give away or Time off, or having to work (sucker).

IF there is anyone that is working on Christmas.. Thanks BUT you deserve it. Everybody gets a turn in the churn. I worked a lot of holidays.. LOL YOUR TURN.

Thanks Though..
