Poor table.

Feel kind of down I couldn't stay for long Sat, and couldn't come Sun. Had to take care of other commitments .

Too wound up after an evening of excellent conversation with OJ, Mike and Luis, must type up impressions.

*Obrado AMT hybrid - hot mess. Little bits of the frequency spectrum sound good, however the crossover is a prime example of messing up phase response so much that the result sounds hollow and images like someone is playing kittycorner across a wall. Yet then the song hits the right notes and for a few seconds the headphone sounds promising. Let's call it a work in progress as the rep was very welcoming of critical commentary.

*Audioquest Nighthawk - muddy, indistinct, warm in a boring way. Looks cool, comfort's all right, but the plankton have been buried under a layer of cement.

*Hifiman HE1000 - A solid effort. Very good bass impact and definition, precise layering of instruments. It is sort of an HE-6 by way of the 560; and while the sound is not as troublesome as with the 560, there's still that treble edginess that the HE-6 has. The pricing is ridiculous and while it feels substantial, the design is gaudy and the peeling veneer is a bad joke.

*EL8 Open - OK, a little grainy, not a huge departure from the Audeze house sound. Excellent European industrial design, though this one should also ditch the woodgrain veneer. Yes, I get it, there's a visual signature. It doesn't inspire the desired response.

*EL8 Closed - weird, underdamped and yet bass light. Wispy ethereal sound with some medium peaks which may be corrected by modding. Sadly it seems that Audeze took the minimalistic byerdynamic approach of sticking a decent driver in a metal cup and letting those two fight it out. Also the overly complex many-pinned connector kept cutting out the sound in two of the pairs I've listened to.

*Fritz speakers - Great down to earth design, Fritz's minimalistic approach is to get as much of the crossover out of the way of the drivers' sound and the results are as good as fancy bookshelves which cost three times as much. I am now lusting over the aircirc.

*Edelstrow's modified 007 - it's an interesting idea to decouple the tensioned metal headband arch from the driver cups with a layer of sorbothane. I'd like to experiment with something like that and I think the effects are both audible and beneficial.

*Stax Sigma/404 hack - I just can't get behind the sigmas.

*SRX Pro hack - nice smooth tonality, rolled off bottom octave. Good deal for a couple hundred dollars if you aren't a basshead and you can find one for sale to begin with.

*Frank's new amp with the 4070 - beautiful at lower volumes, lush and intimate. Listen loud and you have to deal with a strong forward upper mids (~1khz).

*ES 10 - enjoyable, not neutral but still satisfying tonally (apparently despite the measurements). Good headstage for a small closed 'phone.

*PM3 - careless v-shaped EQ ruins vocals with sucked out mids. The bass and treble are merely adequate, so I prefer the HE400 for the money, where the 400's excellent bass makes up for its crude brightness and fuzzy midrange. I'd love a good sounding beautifully built headphone for 400 bucks, but with Oppo's lineup you really have to step up to at least the PM2.

*1964 A12/A10 - the A12 has a tasteful bass boost and satisfying heft, while the admittedly more neutral A10 does not sound quite as endearing. Both roll off a little too early in the treble for my taste. Otherwise they are solid enjoyable headphones. Their high price lowers the value proposition, leaving the UERM as the better deal with better sound.

*Geek Wave - I spoke to Gavin about their engineering choices and it is clear that these guys know what they are doing. Because of this I have regained some confidence in their ability to deliver, but I also hope that they will decide to strive for greater humility and a sharper focus in their business practices.

It was great to see everyone and to meet more pirates. Unfortunately it was sad to see the new CanJam accompanied by a dwindling community spirit and tainted by crass commercialization. If this is the way that things are headed then I'd rather stick to smaller meets. Nonetheless I'm thankful for the effort so many people put forth to make the best of the situation.

My impressions of this headphone really didn't match what I expected to hear from a "nano" diaphragm, so I asked Fang how thick the diaphragm was and he said "I can't tell you."  I guess it's on the nanoscale, but that could mean anything.  It sounded more like 3,000-7,000 nm thick though so maybe the nano thing is to generate some buzz.

One possible thing to consider in case of he1000, compared to stats would be the added weight of voice coils on that diaphragm. It is entirely possible that the HE1000 even if it has a sub-micron diaphragm, turns out to be a lot heavier if you consider the coupled mass of etched coils compared to a similarly thin stat diaphragm.
I wonder if that can explain some of your findings.
