Nearly all manufacturers do not advertise/exhibit their product measurements? Why?

@prof  So, you are a firm believer that all digital cable, if correctly made, sounds the same.  So what I say is snake oil.  That's where I am 100% certain you are mistaken.  I stated you can believe what you want but don't imply that I am wrong because I didn't test measure the differences or that I am being deceived (or all of my friends and experts are also being deceived).  Go back to ASR's snake oil forums and write all you want about how all digital cables sound the same, I don't care.  There is an immense difference in sound from the six different cables I tried.  

This is as silly as my neighbor who is an electrical engineer who thought all power cables should sound the same with a $1/2 million system that had major frequency irregularities and sonic mush.  He often changed expensive equipment not knowing why they didn't satisfy him.  Just one superior cable on his amp and he was convinced he was wrong.  After replacing all six power cables, he admits that scientifically it is unexplainable but the difference exists.  You think he is being deceived now?  That he is a fool too?    Yes, I guess based on your certainty that all digital cables sound the same that power cables also sound the same, unless you reserve your "truth" only about digital cables.

After replacing all six power cables, he admits that scientifically it is unexplainable but the difference exists. 

Science trivially explains that.  You mad a change, he listened more carefully and now he "heard" more detail, air, etc.  Nothing had changed in the sound.  It was him that changed because our hearing is elastic and 2-way.  A comparison causes our brain to work differently and hence we perceive things differently.  

We prove the above two ways:

1. We test the person blind and repeat at least 10 times and see if he gets > 8 right.  Every audiophile tested this way has failed to hear the same differences.

2. We perform measurements to see if there is a difference or not.  If nothing has changed in the waveform coming out of your audio device, then your listening test protocol is wrong.

All of this has been known for decades.  But some audiophiles refuse to believe it.  No amount of explaining the simple facts of how their perception works makes them change.  They go on wasting money on useless audio product after useless audio product.

I have tested a number of digital audio cables by the way. The last one was the $1,800 Nordost Tyr 2: 

I also performed listening tests and found no differene.

Before you come back and say you can hear what I can't, turn on a video camera and perform the AB test and repeat 10 times randomly.  Unless you can show this, you have no case.  None.  You are simple unaware of how your hearing and perception work.  

I was aiming for sympathetic humour, not trying to insult you, sorry if it misfired.

yeah @axo1989 I wasn’t sure if it was humour or an insult, so I picked up a travel book at the newsagent. 😎

I do a bit of mentoring for workmates, and they are pretty skilled, but occasionally they like a pointer. That is about as close to teaching as I get.

I suspect that some of the posters here have made retirement or alcoholism a real thing for their teachers.

That he is a fool too? 

Folks used to think you caught a cold because the air was cold.  This didn't make them a fool.  They just didn't know that it was caused by a virus.  Every bone in their body thought it was the cold weather because that is when people generally caught cold.  It made layman sense.  But simply was not true.

Professionals in every field know of things that lay people think are true but they are not.  In audio however, folks walk around ignoring what the science/engineering says.  They think they are so smart that they have figured out things that eluded those people.  

So no, he is not a fool but was fooled by you.  He didn't know everything I just explained.  You do but still go on causing people to believe in nonsense and cost them money.

I've heard $15+K cartridges and they did sound great with my hot stampers.  They don't typically sound as good with my lesser pressings, mono LPs, etc.  That is why I chose to step down to a Dynavector 20X2L.  One friend who is an LP only expert who is seen all over the Southwest at shows selling high end jazz as well as rock and classical agreed that his Dynavector 20X2H played more LPs better than his current Dynavector XX2L.  When the latter wears out, he will return the former.  Three other friends with 3,500 to 8,000 LPs also use the same cartridge, one stepping down from the Dynavector D3.  The 20X2 sounds great on so many LPs.  

@fleschler it would be neat if we had a way to avoid the first $15k cartridge and just go straight to the better one - which is also cheaper… sometimes cost is not the best metric.
