Best DIY power cable. Why not make?

Todd - they are in the process of re-sourcing that gauge wire.

However - they do have some stocks left of the previous wire, but in order to purchase it you have to send them an email and they will setup a manual order

Here is the email they sent to me...

Hi Stephen,

 We are replacing this wire with 10 awg product that is of the same Mil Spec as the rest of our Mil Spec wires so although we do have stock we have removed it from our site. If you would like to order some Lyn can put through an offline order for you. We have 250 ft of each colour in stock cryo treated.

Alas, I do not know what that manual process involves - sorry

Try emailing them at - sales @ takefiveaudio.com 
- I had to put the spaces each side of the @ in the address to prevent this interface from removing it

A fellow DIYer could not get TFA to deliver to Bulgaria, so he sourced this  wire and reported excellent results

Hope that helps - Steve

You are just adding one more, unnecessary, connection point to the chain. Spades can come loose or break.

I completely agree with you here.  It is one more connection and one more type of material for the signal/electricity to travel through.
They are also bad for speaker cables, though, and for the same reasons. (in theory).

Thank you Steve!

For those that poopoo on wire. I posted this on asylum a few weeks back. I was once in your camp too...

Also my shop HIFI Buys loaned me AudioQuest Hurricane power cocrds to try. I poopoo'd these of course. It's wire, it's power wire. Hooked 2 up to the Mac 601 monos, Well crap.... ok so maybe it's me. I sat the wife down who really did not want too. She said Alan had found another sucker. She and I both heard a level of grudge removed that is very real. Small but sweet. I really did not want my Amex near these but even she said go ahead lol. Interesting that the test on the AR Ref6 was kinda a no go. I think it's better but not for the money, the amps a no brainer. Who would have thought, it's wire....
