Jude E-peens Tyll and Gaslights Us with Alternative Facts

Glad to see you back bro! You have some catching up to do. So do I.

 

@spwath 's measurements don't make me want to drink a TaB cola. He's got some more work to do.

 

Thanks! It's nice to finally have a bit of free time and catch up on the forums and ol' pals.

 

Here's Marv's measurements processed with my TrueCompensation™ (proprietary technology) system:


See? Way better than anything else on the planet!

 

Reckon that Jude's box can keep in screams? If someone brings a padlock i have an idea, it involves ibuds, jpop and ducktape.

 

You are being watched. We hope you understand even if you don't agree.

 

I would like to offer several observations about this.
1. If you have the money, you can own the equipment. It does NOT automatically follow that the owner is either qualified or competent to use the equipment, capable of validating data collected or interpret the results correctly.
2. The thickness of the acoustic materials shown is likely to be somewhat effective above 1000 Hz. It takes 4 inches of Auralex MaxxWall with several inches of spacing from the boundary to have effect down at 125 to 200 Hz. Below 125 Hz requires A LOT MORE high density material and much larger spaces.
3. Faraday cages are absolutely not needed for headphone acoustic measurements unless you are living directly below a 50KW transmitting tower, in which case the measurement equipment outside this box should also be in the Faraday cage.
4. Positioning of the headphones with respect to the microphone has a tremendous effect on the data acquired and displayed.
5. Changing parameters of the measurement system has a tremendous effect on the data acquired and displayed.
6. Audio and acoustic measurement systems are complex requiring considerable effort learning the principles of the measurements to obtain useful results. Appliance operators (those that can run the preset scripts but don't understand the principles) have a low probability of obtaining useful data and are likely to fool themselves and others.
7. Given the personality of the individual being discussed, I am suspicious of the several years in the making claim. I suspect the moment the equipment was acquired said picture was taken and put up for all to admire.
8. I am more inclined to trust data acquired by a knowledgeable, competent, experienced person using modest equipment such as a QA401, ARTA, Scarlett 2i2, emm6 microphone and a modest but decent oscilloscope and DMM, than an unqualified and potentially incompetent individual running a full on Klippel research analyzer ($100K) and a HATS system.

Warning - Personal Opinion Ahead!
The owner of this HATS measurement system does his readership and sponsors a disservice by demonstrating lack of technical understanding and competence for all to see. It would appear the only reason for this is an attempt at bullying the more technically competent but less well funded contributors of many forums and fooling a fair number of his technically ignorant members of the forum. For those that would be outraged and my use of the term ignorant please remember that ignorance is correctable. Stupidity is forever. -AB

 

Just to put it in perspective, this is the build log for a measurement chamber from a PC website: http://www.silentpcreview.com/article876-page1.html

I'd believe that took 2 years, not that joke Jude posts.

 

The various systems may not necessarily directly compare, but trends are observable. When one specific set of measurements seem at odds with trends from all others, we call that an outllier, to be suspected as not representative. In this case outlier appears to apply in more than one meaning.

 

As my politically incorrect golf instructor used to say, "It's the Indian, not the arrow." Buying a $2,000 driver is not going to suddenly make me hit the ball farther than John Daly (not that Tyll wants to be compared to John Daly).

 

I understand why everyone is annoyed with this, I am too. It definitely was a "mine is bigger than yours" display and it was not required at all. The problem is that no matter what anyone posts here or there, he's going to continue doing the same things he's been doing.
That forum in general misleads loads of people, I've been mislead into buying gear by the people there in the past but as I grew I saw through it and found this place.

And now that we are here, unless there's something that one of us can do something about it, I dont think its worth directing energy towards him or his forum. Seems like the more we do it, the worse it gets. Same with all the other bad stuff in the world. Let's just try balance the negative he puts out there by putting out positive information of our own. Most of you guys already do this without needing to do it consciously anyway. One day, he will get hit by his own wall of karma.

 

Silent PC Review. A must-read site before buying so much as a fan for a PC case. No audiophool stuff, just how to make you PC quieter.

Coming back from that tangent/plug, I think I remember reading the history of their measurement systems. It is a different thing, and It might not apply to headphone measurement any more than Jude's little box would be good for measuring the noise coming from a PC. Given the cash, I guess one could order the stuff and have Jude's toys set up in no time. By the way, I didn't read it all, I couldn't stand it: I thought the Faraday Cage was a joke. It isn't?

He probably should have spent the two years learning how to use it all. I speak as one of the technically ignorant who used to think that a graphic equaliser must be easy if the interface is pretty enough: at least I learned that I was wrong. And I'm still trying. I'll let you know how I'm getting on with having a real camera for the first time in decades. In a year or two.

Seems to me to always be a good idea to try to find out what one doesn't actually know. And everyone should read that paper by Pfennig and Dopelganger* or whatever their names are. Accurate memory for details: that's not one of my strengths either!

*Googled... Dunning and Kruger.

 

I had about a 20 minute conversation with him at the S.F. meet and as the son of a lifelong businessman I think my Dad would classify him as "a slicker". Sort of the "greed is good" Gordon Gecko type. Money first and last no matter what damage is done or who gets screwed. He also has a fear of T-shirts for some reason. No negative energy here, just an observation.

 

What I find even funnier is that this even shows that Jude isn't consistent with how he presents his measurements. The scale is totally different on the Z1R measurement than on the Utopia/Elear measurement. Nobody with 2 years of experience would make such an obvious mistake. Seriously, that annoys the crap out of me. Right now all three of his measurements had a different scale on the plots! Get your shit together Jude.

 

Thanks for articulating this. It's this point that should be the takeaway here, not just that it's old Jude up to his usual tricks. I see it less as a bid for Sony sponsorship and more a shot across the bows of the personal audio community in general. It's a very worrying precedent.
