Why longer is generally better for an S/PDIF Digital Cable

Is it correct?

Hi,

This article is a bunch of nonsense! Longer is NOT better. SHORTER IS BETTER! That is unless you are the one selling cables, and you charge a lot and by the foot

Check the website of that Empirical Audio guy:
http://www.empiricalaudio.com/
You will quickly understand that he stands to benefit from that B.S.

For a 1 meter SPDIF he charges 419.99$
For a 1.5 meter SPDIF he charges 549.99$
For a 2 meter SPDIF he charges 679.99$

You will find B.S. “explanations” such as:
“The Bitmeister uses a patented technology that allows the conductors to be 50% bare. Bare conductors cause less dispersion (smearing) in the digital signal” than fully insulated conductors, reducing jitter in the digital signal".

“Pure 99.99% Perfect Crystal Silver conductors in
a custom stranded configuration enhance high-frequency response
by minimizing skin-effect and stranding effects”.

What a bunch of self serving nonsense

Teddy G.:
And I thought the reason was to get the SP/dif, consumer crap, as far away from the good stuff as possible - just "because"?

Maybe, maybe not.
I'm sure that he would say the same about your writings.
So apart from the personal ranting where does it leave us...?

Best Regards

As I said:

“The Bitmeister uses a patented technology that allows the conductors to be 50% bare. Bare conductors cause less dispersion (smearing) in the digital signal” than fully insulated conductors, reducing jitter in the digital signal".

This is a none technical BS, and saying so is not a rent.

“Pure 99.99% Perfect Crystal Silver conductors in
a custom stranded configuration enhance high-frequency response
by minimizing skin-effect and stranding effects”.

"crystal silver"? That is a made up non technical BS.

The are a lot of other comments in that "writeup" that are non technical or technically incorrect. He talks about impedance matching, which is a problem that grows with cable length, contrary to his conclusions. He talks about skin effect which is BS in the context of 1-2 meters for a signal with many ns rise at a few MHz frequency. You want to understand skin effect? Go to my site at http://www.lavryengineering.com click on "forum" then "Tutorials" and find "Skin effect". You may then realize the difference between my technical presentations and that crock you are comparing it to.

Sorry. I assumed you could see that what I said is not just a rent. A technical person would see though it it immediately. I keep forgetting that many readers are more into sound production and much less into the technical electronics subjects.
