Sighted Testing IS King!! Silly me - all those years wasted...

It is far fetched. As for any manufacture of any audio component proving anything, you just need to look at specs that most manufacturers put out.

The manufacturer of my cables publishes all their specifications. So? You seem to assume that specifications really convey meaningful knowledge as opposed to simply information. My experience is that by and large they do not. For any component.

Take five speakers with similar +-3db responses from x to y and you will find five completely different sounding products.

Most cable manufacturers that I've ever seen do not provide any meaningful specs. I don't assume that specs are useful. I use the example as when you see a product that doesn't give any specs (as most cable manufacturers are wont to do) such as Nuance speakers, then you need to approach them with more caution than you would with another type of speaker which does provide +/-3db specs. Take it another step when you compare those little minisytems. They purport to produce 300W, but at 20%THD. Specs aren't everything, but they can give an indication, however slight, about how a particular component will sound.

I guess you're not looking at the right cables. Here are the specs for mine:

Let's return to an earlier point you made about the lack of "proof" cable manufacturers provide. If specs provide only a "slight" indication of real world performance (ain't that the truth!), then what the heck do manufacturers of every other components provide as the "proof" of their respective claims? I find precious few ads for ANY components that talk about DBT testing to support the verity of their claims.

Well, I should've specified specs with regards to audibility as in how much it could change your frequency response not just a simple resitance, cap, etc. Maybe there's some electrical inclined people who would care to comment?

In any case, whoever said that most companies provide blind testing to prove their claims? Does this mean anything at all? Certainly not. As I pointed out before, just because people do or don't do something doesn't make it right. In the case of other components, the line of (blind) tests that have been done as to the threshold of audibility with respect to loudness, THD, et al has a long and distinguished pedigree. The R&D sections of these companies use these studies to make better product (hopefully anyways).

The BS detector went off right away.....

The whole installation information section is utter BS, save for the bending radius. Further, they don't even tell you what changes when they DO burn in! Shippiing something in an anti-static pouch doesn't keep them from being impinged by electromagnetic fields, which is a far greater likelyhood. So how culd you expect them to be "maintained" in their pre-burned-in condidtion if you cannot protect them from ALL possible environmental variables? What about UV light? Temerature variations? Those will have an effect on the dielectric polymers used in manufacturing, no?

Then they list the electrical parameters in base units, instead of using industry standard units:

0.00000000004 F instead of 40pF.....an indication they DON'T know what the hell they are doing. Further, there is no such thing as analog and digital capacitance, inductance, or resistance.

As far as I can tell, you can disregard their specifications as meaningful. They could have just pulled the numbers outta their sphincters based on their obvious lack of knowledge of the basic electrical parameters and environmental influences, electrical or physical.

Other than stating the obvious, you suffer from making unfounded assumptions. There are separate analog and digital flavors of that interconnect having different build construction and different specifications. Duh.

As far as I can tell...

Which evidently isn't much given your propensity to assume instead of asking or finding out the correct answer...

...you can disregard their specifications as meaningful.

Aside from the fact that they answer the question posed.

Your ignorance is showing again. Please, please, please show me ANY reference defining digital resistance, capacitance, or inductance. Regardless of whether the signal is analog or digital, the cable could care less. Impedance is impedance, group delay is group delay and resistance, is resistance. ...need I continue?

I have no need to find the "correct" answer you seek, that wasn't the question posed by the person I was responding too. I am able to tell, however, with the information contained in that PDF is bovine scat. Marketing speak. Nothing more. One does not need to assume anything when they know the topic at hand and recognize the worth of what JPS has published: Nothing.

I really am sorry you're so technologically deficient not to be able to see through the smoke screen.

Have YOU sent a set of cables to be measured to verify if their stated specs are correct to either listing in their document? Of course not, you weren't able to spot the fallicy in their ad.

Maybe they felt that because their meter had a digital readout, it was digital resistance......
I'd really, really, really, like to see you measure digital resistance. hahahahahahhahahahahhaha....

Digital resistance, brother, that's rich. It's like that reference Jon Risch had on his webpage once showing 180 degree phase reversals in a cable that was less than 10 degrees in electrical length.....sorry, bad information. That's what you have here, bad information.

You can beat your chest all you want, attempt to impune my character all you want, but at the end of the day, your ignorance shines brightly here.
