Is anyone in the US making power cables like this custom PC cable ad on the Canadian Mart?

Thank you for sharing a link on transparent. Yes some companies do use resistor inside the magic box as well. I am talking about power cables not about voodoo of interconnects and speaker cables.

I started like you and DIYed some of the designs. Namely williewonka’s helix geometry. It’s a cool design. Expensive parts and lot of work and sounds like crap. Nordost Red Dawn for $500 is much better. Maybe your DIY is much better than mine was a long time ago. But making a power cable is not just getting cables and slapping some Furutech connectors on them.

Did you compare your DIY with reputable brands? You can make a copy but it does not mean it will sound anywhere close to the original.

Yes, as I posted below, I still own a pair of $1,300 Isoclean Auto Focus power cords that were favorably reviewed and that I use on my digital gear. The cables I made that sound better on my amplifiers consist of dual 10 awg wire bundles to each pole, so 2x10 awg = 7 awg to positive, another 7 awg to negative, and another 7 awg to the ground, with the positive and negative runs set up in a twisted star quad design to reduce inductance, which is a good thing for both speaker cables and for power cords. Please note the highly rated Triode Wire Lab “Seven Plus American” power cord uses the same NOS Western Electric wire to achieve the same 7 awg, and the same FI-11 connectors, with one difference being that Triode Pete’s family braids the cables rather than twists them in a star quad design as I do. I cannot link you to the exact picture of the DIY cords but they are in the seventh picture from the end of my virtual system pictures here on Audiogon.

In addition to the Auto Focus power cords, I have tried other "manufactured" power cords by Cardas and others. The DIY cables I have made using high quality bulk power cable by Furutech, Neotech, and Oyaide, and a variety of (mostly Furutech) plug and iec connectors, sound as good or better than the manufactured power cords I have tried. I have tried to show you what has worked for me so at this point, you can either try some stuff for yourself or continue to pay for manufactured cords. Not everyone wants to build their own cables and I get that so good luck whichever path you choose.

After thinking about power cable, I came to the conclusion that there are a lot of similarity with power cable and speaker cable in term of how they affect the sound. The power cable is at the front end, whereas the speaker is at the back end. But why? Especially for a power amp, it has to do with the AC to DC rectification. The power cable serves as the front filter and the speaker cable serves as the back filter.

Cheap power cable are like cheap speaker cable: they just do the basic and they can sound fairly decent. But to get sophisticated sound, the power cable, just like speaker cable, have to be fine-tuned to sound optimal, and that’s where the cost comes in.

I made five power cables using furutech parts, Idk what they use for wire in there expensive pc's themselves?  The first cable took about 3 hours to build, the last two for my amps  took less than half the time combined. I used there spades and contact enhancer, fl-50ncf (r) plugs, dps 4.1 cable. Tech flex sleeving,

A very fun project and a beast of a pc. Building speaker cables now. I suggest you do the same as it's not rocket science.

Is it as good as a Ted Denney special? I highly doubt it but it's good enough for your first pc's!
