Audiophiles are rejoicing.

"I told you so! I told you so! I told you so!", they chant.

A recent paper published in the Journal of the Audio Engineering Society titled "A Meta-Analysis of High Resolution Audio Perceptual Evaluation" by Joshua D. Reiss concludes:

In summary, these results imply that, though the effect is perhaps small and difficult to detect, the perceived fidelity of an audio recording and playback chain is affected by operating beyond conventional consumer oriented levels. Furthermore, though the causes are still unknown, this perceived effect can be confirmed with a variety of statistical approaches and it can be greatly improved through training.

From what I've seen in the past, I would say that if the hobbyists themselves become willing to take up the mission, many, many hundreds of man-hours may be available free for the asking. And if they become invested (like Bernie supporters) raising funds $27 a pop (on Kickstarter or GoFundMe) can become a viable financial resource. But I don't think the enthusiasts will go along for the ride with industry in the lead.

Not long ago, I wrote a little article documenting the effects of different filters in a headphone. Soon thereafter, one of the headphone engineers at Skullcandy shot me an email pointing out a company that makes acoustic filter materials for industry. Boy, wouldn't it be nice to get past the toilet paper and get some of the real deal into the hands of hobbyists. So, I followed the rabbit down the hole.

Editor's Note: You just never know what's going to happen in my email in-box sometimes.

After Audeze clued me into how much the different headphone measurement heads vary in measurement performance, I decided to undertake a little experiment of my own. Well...not all my own, I'd love for others to join in! Come see how.

Editor's note: After my review of the LCD-4, Audeze emailed me concerning discrepancies between my measurements and theirs. Numerous fairly technical emails were exchanged, I sent a number of Excel spreadsheets of my measurements for their use in comparisons, and there certainly does seem to be a discrepancy between measurements.

The folks at Audeze asked if they could write an article about these measurement observations and their response to my LCD-4 review. I said, "Of course, I've got plenty to learn on this subject." This article is Audeze's response.

Some interesting times ahead. Before we start, let's find out what you think.

Let's agree from the start that measurements are no substitute for listening when evaluating headphones. The question is, do the measurements serve a useful function?

If you choose the last selection here, you really don't need to bother with the rest of the polls.

Feel free to elaborate on how useful headphone measurements are to you generally in the comments.

How Useful do You Find Headphone Measurements?
You bet, I can tell quite a bit about how a headphone might sound.

I can get a rough feel for how a headphone will sound.

I can't tell how it will sound, but I can tell if they're junk or not.

I'm pretty confused by it all, but I'm trying to figure it out.

Some will, no doubt, say "MOAR IS BETTA!", but let's not go there. Please select which best describes what you see and are looking for in bass response measurements.

Feel free to elaborate on how useful bass headphone measurements are to you in the comments.

How do You Evaluate Bass Measurements?
I'd like to see a nice flat line, and I know what it looks like.
31% (41 votes)
I get the plots, and I like the +3dB boost of the Harman target response.
49% (65 votes)
I get 'em. I really don't mind a gently rolling-off bass; lots of cans have it.
8% (10 votes)
To tell the truth, the bass often seems somewhat different than the plots.

MOAR BASS!!! (Editor's Note: Hey, I said knock it off!)

As J. Gordon Holt famously said, "If the midrange isn't right, nothing else matters." Please select which best describes what you see and are looking for in midrange response measurements.

Feel free to elaborate on how useful midrange headphone measurements are to you in the comments.

How do You Evaluate Mid-Range Measurements?
Of course I get it, and again, what's wrong with a flat line?
25% (31 votes)
I get the plots, and I like the gentle upward slope of the Harman target.
48% (59 votes)
I like a "U" shaped response.
4% (5 votes)
I like a mid-strong response.
8% (10 votes)
I just look for too many wiggles; should be flat I suppose.
9% (11 votes)
So...where's the midrange exactly?

We'll probably all agree that treble measurements are noisy and difficult to interpret. It's mostly blurring your eyes to get the gist of the general trends. Ah well, please select which best describes what you see and are looking for in treble response measurements.

Feel free to elaborate on how useful treble headphone measurements are to you in the comments.

After submitting your vote, you're done. Thank you for helping out!

How do You Evaluate Treble Measurements?
Can we get a holla for a flat line! Okay, maybe a little roll-off.
22% (27 votes)
Heaven forbid an upward spike between 4-8kHz; after that just a little roll-off.
35% (43 votes)
I like the evermore-descending response of the Harman target, all the way up.
28% (34 votes)
I really can't tell what's going on up there.
9% (11 votes)
Don't believe anything you see after 4kHz!

It is, after all, the most hated connector in the audio world.
