DIY "HiFi" cables - and why I don't trust BJC and the likes


After watching these two youtube vid below, I suspect a lot of online so audio cables companies are like these.  They basically use off-the-shelf spool of wire that you can easily purchase from HomeDepot or PartsExpress and dress them up nicely with fancy jackets.  I think BJC falls into one of these categories although for their credit, they don't charge a lot of money.  

I don't mean all audio cable companies are like that.  I do think some well established companies such as AudioQuest, QED ... actually have some real engineering going into their products.  For example, QED has a very unique geometry in their cables that you can't get from off-the-shelf.  It's just that there are too many online companies that give the cable industry a bad name.

  I am not 100% on the side of DIY or commercial cables I am currently using both, I have Kimber on my front speakers, BJC on the surrounds, and home made on the Atmos.

I've read a lot about commercial cables, some of the science behind cables, how a $3,000 dollar commercial cable makes absolutely no difference when compared to a DIY $20.00 cable and you wouldn't be able to hear any difference. I've heard the debates.
I do not know to what extent it is all true, I have not done any side by side testing. Maybe you can get better sound quality with a commercial cable due to quality of components, manufacturing techniques, maybe it is not black and white and there are some good commercial cables and junk ones, maybe DIY are just as good I don't know and I am not debating that.

What I know is that I bought my Kimber because; I love the braided look, they are base models, I bought them used, and they sound fine to me. 

Now BJC, do you know how they are terminated? They are ultrasonically-welded.
This is what drew my attention when I came across them and why I decided to give them a try. Ultrasonically-welded at low temperatures, pretty cool.
If your not familiar with the technology check it out;

BTW something I like about BJC. American Cable, American Technology, American Assembly

Something else I take into consideration with making my own cables is human error. I have been in IT for years and years and have terminated a ton of networking cable. When cost came down on manufactured already terminated networking cable I begin using it for a lot of applications. Buy the length I need, run it, plug it in, verify it is transferring at the right bandwidth, no fuss no muss. Sure I can terminate a cable, test it to make sure it is good but now that the cost is so low and I can't manipulate and terminate cable like I used to with my hands, due to issues.

Speaker cable, what if I miss a strand or two when putting a end on and create a grounding issue? For the cost, peace of mind, and not having to kill my hands, I'm fine with commercial.
I disagree with DIY cables not sounding good.

I have made many, the latest power cord version I made is with pure 10 gauge .9999 solid silver covered with a very high quality Teflon. I braided the 3 conductors lightly and terminated them with Furutech NCF fittings. On the wires themselves I coated them first with Furutech Nano liquid before connecting them into the connectors.

Took a little bit of time to break in, but compared to SR, Purist, Hurricane etc. These are much superior sounding.
So, I say the conductors and connectors are the main ingredient.

Now THAT is a  expensive power cord.
Buy why pure  silver?? and Furutech NCF adds more to the cost.
But why?
Copper carries 110 volts just as effectively/cleanly as copper.
Here is my version of a  copper power cord
Home Depot 12 gague THHN strand + pure copper termianls from china @ $20 for a pair.
I 've made 2 cords, one for the Defy , the other for the cayin 17 mark1 220 volt, plugs into stepup trans. 
Both really nice, ugly, but highly functional.
When the 3rd terms arrive from china,,going on 2 months ship,,,I will uploada  Vid on the DIY of the cord.
You have to break off the clear plastic face plate to get it to work out.
Silver is not going to carry more juice, nor cleaner juice, vs copper 12 ga.  
I'm not sure if the OP meant to criticize all DIY cables or those "cable companies" that are being disingenuous about their added value. 

I completely agree that cable companies that use readily available bulk cable, add some connectors and some woven polyester sleeving, and then charge 5 or 10 times the retail cost of the components while pretending that they have some unique technology are pretty sleazy. 

I don't think this necessarily results in a bad cable - there is some excellent bulk cable made by companies like Furutech, Neotech, DH Labs, Mogami, Kimber, Canare, Belden and others, that offer good to excellent performance. But a DIYer can use the same bulk cable with good quality connectors and achieve the same results (assuming they know what they are doing wrt prepping and terminating) for a fraction of the cost.

I have no problem with companies, such as Blue Jean Cable, that disclose the fact they are using one of these products, and that charge a fair price for the excellent job they do with termination.
