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

USA only Canadian audio mart good luck with that as you can get ripped off easy there.Good luck though.

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! 

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.

Did you compare your DIY with reputable brands?

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.

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.

Many of the very expensive cables have also a magic box. What do you think is in it?

Maybe stuff like this...that was duplicated by an enterprising DIY'er here.

If you want to make a good cable look at anti cables. Their best power cable is $300 and sounds $500. If you can beat it with your DIY than you are on a good path but you can not spend more than $100 in parts.

My DIY power cables made from Furutech FI-11 connectors and really old wire that cost less than $100 sound better on my amplifiers than the $1,300 Isoclean Auto Focus power cables I also own.  Bulk cable from Furutech comes with their in-house treatment and can sound very good when used with some of their well constructed connectors, but it will cost you more than $100.  Bulk cable from Neotech can also be very good although I believe they have reduced their bulk offerings in the past few years.  However, you can purchase bulk custom stuff like the C-MARC cable from Less-Loss.

I agree that some of the very top end stuff would be tougher to duplicate and that a DIY'er would not be able to duplicate the special manufacturing processes many of them use, but using the available high quality bulk cable and connectors can get you well into the range where you would pay thousands for similar sound quality.  Take some cables apart and you would see it it mostly wire and connectors.....and sometimes a crappy soldering job.

Yes. If you are ok with cheap cable than that is how it's done. Most good cables are done very differently. Companies treat wires in house and that is their secret that nobody can reproduce. Many of the very expensive cables have also a magic box. What do you think is in it?

You think that getting a good sound is just putting a wire and connectors together than you live in a stoneage.

Uh, that’s how cable companies start, and short of the folks using special network boxes or maybe special cold weld connection techniques, most of them are doing exactly that....putting wire/cable and connectors together.  I have been inside of more than a few well respected cables and as long as you can get the same wire and connectors you can achieve the same result.  It is far from the rocket science those companies would have us think it is.  The wire/dielectric/geometry combination needed to achieve the desired sound is probably the most difficult part and yes there is a lot of research put into that by some well respected companies but, you can easily purchase the exact connectors used in multi-thousand dollar cables so, if you can get the wire in bulk....

Westminster Lab´ 10 pins replacement umbilical cable for the Lumin X1 is three time , the price of the Audio Sensibility’s one.

The lumin X1 umbilical 10 pins stock cable is about 200 US $ .

@ebm 

I have bought a 10 pins umbilical  cable from Audio Sensibility lately;
to replace the stock umbilical  cable of my LuminX1 .
And I am very pleased with the result   !!

Very good products but not as super cheep, as the one on Canuck Audio Mart though.

You guys are going to get what you pay for. You are better of getting something made professional. You think that getting a good sound is just putting a wire and connectors together than you live in a stoneage.

You also talk about getting six of them. You should buy one for 1k and see what you can hear. You will be amazed. Just buy the best you can afford and forget about DIY.

Thanks for your detailed and thoughtful reply.  Even with $10 per foot wire, by the time I bought the spades, contact enhancer, shrink wrap, and even a cheap crimper, I can't make power cords for what that ad is selling them for.  It's not that I'm against making my own, I just thought the seller had put some thought and effort into his construction, and for the price, they'd be worth buying five or six of them to try.  Then I found out, that he only sells in Canada.  So, it made me ask if anyone knows a similar make up at similar pricing, selling in the US.  

I will definitely look in to the stuff you recommend. Thanks again.

Just be aware the seller did not say the conductors were also made by Furutech, just the connectors.  I also like those FI-11 connectors and use them for my own power cables.  There are a variety of good bulk power cables you could purchase in order to make something yourself that could be just as good or better, if you are inclined.  However, a quick search indicates there may to be less available bulk cable than there was a year or so ago.  If I were looking for an inexpensive option, I would consider the double shielded, 9.8 awg "Gotham 85055 Powercord (Deep Cryo Treated)" at Take Five Audio for $10.99/foot (or its smaller brother for less), but there are many other options from other vendors.  There is no requirement to use techflex on power cables and the quality of that material makes no sonic difference when used to cover the thick PVC typically used for the outer covering of power cables.
BTW, when the seller talks about, "conductors terminated with copper forks" they are referring to these types of skinny fork spades, which actually work quite well compared to trying to twist and "fork" heavy gauge wire so it can be clamped in the Furutech style connectors. 
I only saw " crimped with forks" in the ad you linked but if you want to utilize "pneumatic" crimping, I use this inexpensive hydraulic crimping tool on spade connections and it works great.  I believe a ratchet type crimper could also work well for the small spades suggested.

I like Ice Age. They cyro theirs.

If you need cheaper than parts just buy the Chinese.
