Intona now manufactures "HIFI" USB cables

[louisxiawei]

IIRC, when I purchased the Intona USB isolator, the website was not that "HIFI" orientated. There was no single "HIFI" or "audiophile" word to promote their isolator.  Recently the local dealer told me that Intona starts to produce "HIFI" usb cables. Out of curiosity, I checked the website and found some interesting information and "measurement" (although I personally doubt the figure can be called a measurement) of  "signal integrity" and "impedance", etc.

Intona USB cables are graded in Professional, Reference, Ultimate. Sounds also very hifi.?

 

Sadly, I don't find this made-in-Germany USB cable is certified. I always feel strange that if any "hifi" grade usb cable can be made that good, why don't they get certified?

I'm not the most interested in their SQ aspect as any new adopter will enjoy their purchases without doubt but wondering whether the information provided by Intona makes sense. Since there is quite a lot USB-related topic discussion on this forum, I think it's a good place to start this thread.

 

Anyone is welcome to leave comment on their technical explanation.

I suppose it's hard for any company to say no to free money.

Crap....

last I knew, cable impedance was a linear function of material and cable length, with wire impedance measured in fractions of an ohm per foot. Whats with those

bizarre graphs trying to assert sinusoidal impedance behavior with change in length?

[mansr]

Those graphs are about characteristic impedance. If a transmission line is terminated into its characteristic impedance, there will be no signal reflections. Minor manufacturing anomalies in a cable cause glitches in the characteristic impedance. This results in small reflections at these points. Should they be too numerous or too severe, the signal integrity will suffer. What Intona are doing is, they take a raw length of cable and measure it for reflections (that's what the vector network analyser does). They then cut out sections that are relatively free of imperfections to make the cable assemblies. What's missing is an explanation for why this should be necessary. Generic USB cables work just fine with negligible bit error rates. A more tightly controlled cable impedance will not make an error-free data transmission more error-free.

I applaud the initiative!

but I stopped clapping when I saw the prices.

Maybe at tenth of those prices...

Apologies for the off thread post, but is fairhedon.com a site run by the recently banned member Brinkman Ship?

Yes, I think so.

His name is Andre Marc.  Has written reviews for various online mags.

That is either not the same person as Brinkman Ship, or he goes by multiple aliases in real life as well.

Yes, it is. I'm just saying that Andre Marc isn't Brinkman Ship. I know his real name.

Okay.  I don't know and I don't care.  It just seemed that since @The Computer Audiophile said Brinkman Ship and Fair Hedon were the same (now banned) CA members and that he was a writer, it seemed a too coincidental for a new audio web site called Fair Hedon.

Yes, that's a fair observation. Maybe there is some affiliation between them. I don't know.

I'd be shocked if you're right on this one. Based on all the circumstantial evidence it really points to him being Brinkman, Fair Hedon, and Digital Assassin.

I know for sure who was behind one of those usernames. His name is not Andre Marc.

How sure are you?

neither important, nor on topic, but as I am supposed to be retired (twice) I will await the deconvolution of this mystery...

''The reflected energy causes echo effects which disturb original signal

The resulting effects are similar to those of Jitter''

Reflections can cause Jitter and Jitter at varying frequency will affect the audio signal. Different pieces from the same cable reel will not be 100% identical and in theory will not measure identically.

But what is a resulting effect similar to Jitter , if its not Jitter what is it?

On asynchronous USB, there's not really any clock transmitted over the cable, so as long as it doesn't cause transfer errors, it really doesn't matter at all.

Hi Crenca. If you look at Fair Hedon's avatar on CA  note that he uses the same branding picture on the Fair Hedon site.  So I don't think he was trying to hide the identity match at that time.

Looks like access to this site is now very limited. hmmmmm....it was fully accessible 2 days ago.

 

There is a post on the Brinkman Ship MQA test thread where he lists his home system. A number of matching components came up when reading reviews on the Fair Hedon site.

 

 

 

sorry for OT
