If Lambdas existed with O2 levels of detail, I'd have stayed with exactly this rig. It's a good demo for anyone with the mistaken impression that Stax don't have bass, specially if you put Herbies dampers on the tubes. My HD-800s are on the chopping block too for this reason, even if they are the technically better headphones, they aren't as much damn fun, and anyway, once my eXStatA is built, they likely don't stand a chance.

Could you clarify on what you meant by 'technically better'? And almost every Stax is a good demo for anyone with the mistaken impression that Stax don't have bass. The same can be said about Stax headphones being extremely expensive.

Jim, is that a Steve creation? It looks awesome.

Dr. Wood's work, indeed.

Yep, Al beat me to it but it is a Dr. Wood stand. As with all his creations the detail is marvelous and my piddling photographic skills do not do it justice.

Here's a dumb question, but where is the flat bit of the otherwise circular O2 pad actually supposed to be oriented relative to the outside of one's ear?

I usually have the seam pointing forward and slightly angled upwards towards the temples. That's how the SR-Omega is but how I've used my set from day one.

Toward the back of the ear, I think. At least, that's how I wear mine.

I wear it with the seam somewhere between straight forward and angled slightly up, whatever ends up being the most comfortable.

Same. Well, when I had them.

Seam slightly angled up.

Thanks gents. I had the seam more toward the vertical initially. This is indeed better.

Since we are on the subject of the earpad position, do you guys position your ears inside the cups farther back toward the thicker part, or more forward toward the thinner part? Although there is much smaller space inside the O2 than SR-Omega, there is still enough room inside to move your ears around.

I generally wear them slightly more forward so my ears are more towards the rear of the pads.

There really isn't a whole lot of room for my ears to move inside the pads so towards the back for me. Same with the SR-Omega

I have little room to move the O2 around my ears, but I tend to place the drivers to the most in front I can. BTW, pads seam in front and upwards for me, more or less matching the arch of bone (zygomatic arch) going from the temporal bone to the zygoma (cheekbone). What I've found helps for a more frontal presentation is opening a bit the rear arch of the headband and closing the front one, so the drivers slightly rotate inwards to match the pinnae orientation.

Ditto, making them just a bit angled inwards does help with the imaging.

Now I'll get back to listening to the rebuilt ES-1...

Fat towards the back would make sense to me, since my ears are farther out from my head towards the back more than towards the front. But 100% of the time, I'm listening to someone else's, so "the way they have it" until I get my own pair.

Yep, that was my initial thought when I first saw them, but seal, which is crucial to have bass response right, comes from fine tunning the pads position to adjust to your own head-ears shape. So you may end up with the fatter part a bit downwards. The seam is in the thinner part, so it would be placed to the front.

This. Also, I've found that it takes turning the pads and the outer rings so that the cables are oriented correctly.

With the 4070's I don't have any of these problems.

This. Also bent the arcs slightly to angle the earcups to better fit my head.

Indeed!

I admit to having a bit of 4070 lust...

Modded the ET1000 some more. Replaced the thick stock cotton damping with some thin craft felt, and used the same stuff as a layer right up against the outer screen. Which btw is really heavy, seems kind of like metal. Weird. I also fully ripped off the really thin fabric over the drivers. Some of the insane speed is back but it's not bright anymore. I remember someone mentioning something about treble impact. This has it.

It also now has boatloads of bass.

True but that is one heavy headphone...

Same here. I only needed a mild adjustment but I've seen pictures of some truly drastic arc bending. I believe Darthnut had his arc's in a roughly 90

They are about 4 oz. heavier and closed but I'm getting used to them. When you have been using the PS1000, the weight of the 4070 is not a noticeable.
