Archimago measures Ethernet cables

What @Stereophilus was saying - which I understood to mean ... the simple measurements that current technology allows us to take does not cover all the sonic differences that we can hear,

That’s also what I took his comments to mean. My response is unchanged :)

There are (many) unanswered questions that require a thorough methodology to reach valid conclusions about what we hear when we reproduce recorded music and why

Do any of these questions relate to Ethernet cables?

? nice.

 

Clearly there are and it is why we are all here sharing our thoughts somewhat amicably.

 

Archimago prodded his "dead" parrot with a stick and concluded it was dead when it didn't  respond.  I'm not yet convinced that the only explanation for a bird that is prodded with stick to remain motionless is death.

If there are indeed studies that show that in the absence of other known and understood reasons, there are audible differences between Ethernet cables then I agree, science should investigate.

Are there?

 The denial of audible difference in the absence of measurable difference is really just lazy science.  There remains a great opportunity to explore and expand the science of audio reproduction and human hearing. 

What do you suggest they measure?

There are none that I know of, but that is not reason enough to not explore further.

Firstly, please understand that like you, Con, I have a university and post-graduate education that encourages critical thinking.  In this forum I am applying that critical thinking to a hobby I indulge.  I am not specifically proficient in the science of music reproduction.  However, from what I know, my suspicions are:

1) that our current knowledge significantly underestimates our ability to differentiate subtle changes in a complex mix of air pressure frequencies (ie music).

2) that we neglect whole system effects when we measure individual parts.

3) our current controls for minimising the impact of psychoacoustics (ie blind testing) are poorly understood and poorly implemented in general.

Our current knowledge of gravity doesn’t allow us to incorporate quantum mechanics. The theory is incomplete and there is a vast amount science doesn’t know. 

But if I claim my ability to levitate is evidence of that incompleteness, I fully expect scientists to think critically and decide no further investigation is required.

Firstly understand that I don't have a university education. I do however have extensive experience in the field of electronics and electrical engineering principles.

 

1) Our current knowledge of electrical principals and technology enables us to examine the electrical signals, that are applied to the transducer, to produce those changes in sound pressure to an infinitesimal degree.

 

2) It is appropriate to examine individual parts of the system, when claims are made that certain individual parts do make a difference, when well researched and proven electrical engineering principals would say they didn't.

 

3) yes. But that is more a reason to believe that any any perceived difference is a product of psychoacoustics, when there is no hard evidence to support it.

In regards to your claim, yes, that would be reasonable, at least for now.  But that will not impede the further advancement of knowledge.  It would naive to think we won't someday have the means to explore your claim with more rigour.

 

For the reasons I mentioned above, the science behind music reproduction remains relatively simplistic.  And it overlaps with the science of psychology, which is unlike the other sciences in many ways.  We still have much to learn.

Data transmitted over ethernet cannot sound different if it is error free.

Maybe, I don't know.

 

But I do know most people around here said that software players can't sound different to one another because It's all 1's and 0's, it seems like a fall back to any questions where binary code is used.

Encoding, decoding and playback equipment can alter the sound, the data doesn't change. Spend you money on playback equipment rather than ethernet equipment.

To your knowledge and the current popular understanding of it.

 

Like many other things, I'll wait and see if things change in time :)

And you will note that I was careful to describe that the concern was not with the specifics of the electrical signal.

Yes it is appropriate to do that, but there is possibly a broader issue at play that is neglected in isolated testing.  This is an unproven theory, and conjecture on my part.

Sure.  But I'm curious and I believe we can do better than resorting to questionable methodology and faulty assumptions.

That a poor example to rational thinking............. Netflix :lol:

 

Anyway, enough fun, I'll leave this for the people it matters to most.

In fact it is a very good example of the robustness of the protocols and stack, working as designed over a variety of equipment and connections while preserving the integrity of the jitter prone data.

cum on, you can't use that sort of language in a discussion about whether USB cables sound different to each other...

 

Geez next thing you'll start bringing logic into the discussion as well.
