I spent the weekend listening through Chesky's new Ultimate Headphone Demonstration Disc and a few of the albums released using the Binaural+ techniques and technologies. First observation: Man, did I get sucked into the music a lot!

Second observation? The first would have been enough all by itself, but the overarching impression of about 12 hours of listening in the past few days is that I had been in the presence of not just the music, but with the musicians as well. Very unusual, and very satisfying.

Scott Wilkinson is celebrating his 200th installment of "Home Theater Geeks" and has kindly asked me to join him for the party over on TWiT.tv.

The show will be broadcast on TWiT.tv live TODAY, Thurday, April 3rd at 5:30-6:30PM Eastern Time (2:30-3:30PM Pacific). I hope you'll join in to view. If you log into the chat session you can ask questions and watch people comment on the dialog as it happens. Quite fun, I really enjoy doing it.

Both audio and video will be available afterward on the Home Theater Geek page on TWiT; for real Podcast is available through iTunes here.

See you then!

Maybe I'm more of an objectivist than I think I am. I've got a some streaming speakers in the house to review, but I simply can't bring myself to do it without a basic frequency response measurement.

Here's what's cooking.

As many of you know, Sean Olive and crew over at Harman International are developing a new target response curve for headphones. In this post I've modified InnerFidelity headphone measurements on a number of widely known headphones in order for you to have a first look at what the frequency response of headphones might look like with this new curve.

I'm thinking it's a pretty good start. What do you think?

The first step is always the hardest: the "Wall of Fame" page for headphone amps makes its debute.

Darwin said, "As neither the enjoyment nor the capacity of producing musical notes are faculties of the least direct use to man in reference to his ordinary habits of life, they must be ranked among the most mysterious with which he is endowed." Indeed. Why is music so pleasurable?

More to the point—of this article—if pleasure can be measured by brain activity monitoring, could audio performance be objectively measured where it counts...in your head?

If I think back five years or so, I would guess that Pono would have looked like the break-through audio product for headphone enthusiasts. From the comments I've read over the last couple days it looks like audio enthusiasts are giving it a bit of a squint-eye.

Is Pono the magic bullet we've been waiting for to bring high-quality audio to the masses?

I can't believe it...NwAvGuy has come up yet again. In a recent post on the IEEE Spectrum site called "NwAvGuy: The Audio Genius Who Vanished", David Schneider provides a short summary of NwAvGuy's brief stint as an audio industry influencer, and informs us about problems with the manufacture of the O2 headphones amp due to it's Creative Commons CC BY-ND license which forbids derivative works. The power input connector specified in his amp is discontinued and the replacement part has pinouts that are too large for the holes on the circuit board. Unfortunately manufacturers of the O2 are forbidden by the license to change anything in the layout...even something as simple as the hole sizes, and to make matters worse, only NwAvGuy has the files needed for proper adjustments. Evidently JPS Labs has found a workaround and is modifying the boards because, as John Seaber sees it, "... (it's) okay in this case because it didn’t violate NwAvGuy’s fundamental intent." Personally, I'd agree with John in this case, but the ethical issues remain a bit uncomfortable none-the-less.

What I'm more interested in today is whether you feel NwAvGuys contributions to the dialog in the headphone enthusiast community were fruitful or not. I know he did a superb job of pissing numerous people off in on-line forums, and found himself banned from numerous sites. But he also did a great job of measuring gear, and providing quality technical information for hobbyists. Trolls come in two flavors: those the piss us off and are destructive, and trolls that piss us off but make us think leaving us the better for their annoyance. You can visit NwAvGuys now abandon website here.

Which one do you think NwAvGuy fits into best?

On the one hand, NO! It's a silly question, far too simple to be useful. On the other hand, more ears will be listening to music on headphones than ever before, and hopefully they'll be getting their first exposure to well reproduced audio.

Okay, let's talk about it.

We never did get those flying cars we were promised, but we're getting ever closer to being wired up like the Bionic Man.

If you read these pages regularly, you likely love music well reproduced on headphones. What's not to love? The bigger question is how come more folks don't love music well reproduced on headphones?

Audio researchers find that trained listeners yield more consistant test results in subjective listening tests. Well, I suppose that means you or I would do a better job evaluating gear if we had some training, no? How does one go about getting this training? Do you have to work for some big audio research organization?

NO!!! Now Philips has release a version of their training program on-line—it's free, and it's fun!

Harman researchers have continued their march forward to find a subjectively preferred target response curve for headphones. Reading their latest paper has me hearing the last nails being driven into the coffin of the diffuse field response for headphones...

...thank goodness.
