Blue Jeans Cable goes High-End

BJC is bandied as a serious company. Now it looks like they're seriously after a slice of the lucrative high-end cable pie.

Can you think of anything with a higher added value than high-end cables?

Saffron?

And this one product they are marketing makes them a joke? 

I'll just ignore it and continue to buy their other cables, which aren't expensive, are custom and well made, and come with measurements showing they meet spec.

Yes. Moreover, it shows that they are no longer trustworthy. When a company sells even one product with a hint of serpentine grease, it means anything they say must be carefully scrutinised. Reputations are hard to build and easily squandered.

I’m not sure how this is new information. If heat didn’t radiate out through a vacuum then Apollo 13 would not have been cold soaked after turning off the heater, heck they wouldn’t even need one. Another question is how did they keep the astronauts from getting cooked by the sun or freezing when not in sunlight?

 

so many questions...

 

I understand space isn’t a perfect vacuum but it’s sure as hell empty enough that normal modes of heat radiation won’t work. 
 

maybe I should have paid more attention in Physics classes. 

This is a different effect entirely. Spacecraft have, obviously, always relied on infrared radiation to lose excess heat. The article talks about the discovery of heat transfer between two objects separated by a vacuum exceeding the amount of IR radiation. This effect works only on the nanometre scale, so it has no relevance for spacecraft.

Yes, only buy cables with at least 99% ideological purity!

 That's BS. Every company has a right to sell premium products , and just because they have 1 line from Belden that costs a lot more for them to buy too, does NOT mean they are no longer trustworthy. If a customer can afford to pay more, then it's their money and their choice, and they don't need you or anybody else to save them .

 Would I buy them ? No, but that's my personal choice, as I believe that there are other ways to get small improvements at a modest cost.

All you are doing here is reinforcing your own rigid belief that all half decent cables must sound the same, and hatred of virtually all sellers of high end products, just as you did with Uptone.

To you, they are ALL Snake Oil purveyors.

Sure, they have the right to sell what they want, just as I have the right to judge them however I want for so doing.

It's a different phenomenon than radiative heating. But I can't see that it's very surprising. There are all sorts of forces/particles being interchanged all the time in the "vacuum," and why should phonons carrying heat energy be an exception?

 

See https://en.wikipedia.org/wiki/Casimir_effect and https://phys.org/news/2018-07-uncovering-interplay-famous-quantum-effects.html .

 

Maybe I am having a really dense day, but I don’t see how they can eliminate radiative heating. The heat from a spacecraft also has to radiate out a few hundred nanometers, and beyond. Either, they are saying space is full of particles that can carry the heat energy away from the spacecraft, or...?

[Ralf11]

the mode of EMF transmission is different from anything proven before, and involves quantum effects (quantum field theory), not conventional Maxwell silver hammer stuff

Photons vs. phonons. 🙂 I don't know whether they measured heating over and above what one would expect from infrared, or set up the experiment to eliminate infrared radiation.

Ah that brings back some memories 😊. In a previous life, my research involved phonon spectroscopy on 2D electron gases using superconducting tunnel junctions. I'm sure there's some application to audio... if people are happy having their rooms below 1 Kelvin.

Oh please, BJ cables makes good quality cables at a reasonable prices.The new stuff is a separate thing, they even brand it differently.

 

Hmmm ... BJC says this on their website:

 

"We can sell you some very expensive cable, if you want it. We have some coaxes that could endure baking in the oven, like Belden 89259 or 89248, and these cost a lot of money. If your application requires that, then these are the best to use because they won't melt and burn up; but if you aren't asking about special applications and the like, our standard recommendations -- which often are also our lowest-priced -- are truly the best product we know of for the application, so don't let the presence of a costlier alternative on our site make you worry that you're not buying the best cable for your needs."

How can they say this while at the same time selling the Iconoclast cables which are just expensive, not actually better for any audio application? Hold on, I think there's a word for this ... hypo-something ... hypoxia, no that's not it (though one wonders if that wasn't involved too) ... hypocrisy. Yes, it's called hypocrisy.

Doesn't really concern me. They are a cable company, not a religious ministry, politician, or social organization.

To me, the pitch for these cables is dead simple: "made for those who appreciate the high quality of Blue Jeans Cables, but insist on paying more".

Haha that's probably not far off.

 

If i'm going to buy an expensive cable at least wine, dine, and voodoo me!

BJC sells standard well-measured cables, and also expensive but well designed cables that costs a kidney. I don't know why selling an expensive cables where the designer publishes the measurement data can be such a blasphemy, where they did not force or even persuade anyone to buy. They're just giving the market a choice. They didn't increase prices of their standard products; they didn't promote the Iconoclast series with crazy marketing; they even put it at a separate website that the normal BJC customers might not even find it easily (no marketing people will do a move as stupid as this).

 

Also, the now sell a flexible version of interconnects for professional use at way more affordable price.

 

Come on guys, did anyone read the design papers and are willing to discuss whether the design and measurements are up to snuff? Or is this going to continue deteriorating as a scream fest?

Many companies sells both rather inexpensive and very expansive cables. AQ and Wire world are two examples. Blue Jeans Cable have made some statements about expansive cables in the past that can be interpreted like they are no better than their more reasonably priced ones.

 

I have 3 Blue Jeans Cables and have find other cables in the same price range to "sound better". Two examples are Supra and Cable solutions.

[Ralf11]

what is an expansive cable ??

I have been shopping for cables to finish off my system and right now am using  Belden, Grimm, and Gotham.  I have looked at more expensive audiophile offerings, however.  There seems to be a lot of similarity in the the approach.  I guess you can only do so much with wire.

 

1. Stranded cable is rare among expensive audiophile offerings

2. Most companies seem to use multiple thinner solid core conductors emphasizing the purity of the copper

3. Various sometimes "exotic" materials are used to cover/space the conductors including natural materials, tubing, air, etc.  Weaving is also big.

4. Silver and sometimes gold enter the equation as you move up the line

5. Really expensive cables tend to be rather thickly constructed

 

The Iconoclast seem to be following suit with their design.  I believe Blue Jean just puts it all together for them, like they do with other Belden cable.  I suppose that may involve weaving the wire as well, but I don't know. 

 

[Ralf11]

none of that matters, with the possible exception of cone driver speakers that have impedance changes with freq.

Can anyone tell me how make a low inductance and capacitance cable?  The figure given by OP seemed low enough and the only other cable falls in this category was the Kimber ( one of the series). Sanders Mogami cable got very low Inductance but with high Capacitance. I don’t think buyers really got a choice but to pay  the asking price.

Had a look around ... this seems to be pretty decent, at least as a starting point, https://diyaudioprojects.com/Power/Low-Inductance-DIY-Speaker-Cables/.

Saw that before but then decided to go for Mogami. Can’t remember why?
