DIY cables Vs Mass market cables.

Yes lol ..I've also seen spools of this stuff. I don't know where the owner purchased it though.I looked at this wire close up..it looks like some of the copper strands are dipped in Aluminum or Tin..not sure though.
"Audiophiles shouldn't fall for this". Yeah ..I agree but some refuse to see it any other way. I say let them blow as much as they feel comfortable..it will help with the audiophile nervousis.
Cheers

"But as Trelja says, JPS just buys whatever it is from someplace like Belden (which undoubtedly calls it something different), probably for pennies a foot--or a bit more if you want a custom insulation job, which is where that extra-special "dialectric" comes in."

That sounds great and all since several of you have said that, but so far my request for a formula for a better sounding cable hasn't been offered. Proof is in the pudding.

Also, there is such a thing as intellectual propery. Which means if you don't know their formula, then you can't make what they make without buying their cable. So, where's the better formula. I will try it and be honest. I do not care about winning an argument here, and will readily thank you for providing information on a DIY forumla that will save me money and sound better than some of my favorite cables. I'm being serious, not sarcastic about my request.

There is no intellectual property here. You buy some cable from Belden. You solder some spades on the end. That's the formula.

Darn, Pabelson, you make it seem a lot less glamorous than the advertisements!

Proof is in the pudding

You are quite right. There are very many formulae -- do try googling the subject. OTOH, a simple experiment is to use magnet wire (i.e. coated copper wire -- choose awg according to application). Make single core cables for the spkrs first -- you can get away with unshielded. IF you use terminations, make sure yr soldering is top-notch (not talking about using silver/gold/platinum solder; I mean making a good connection). Try these out.

Quite a few parametres affect how the connecting wires (cables) connect (sorry). Load & source impedance is one of these. Accordingly, different wire "recipes" can sound slightly different. But you CAN diy cables & obtain satisfactory results...
