This marks the first time in recorded history that Wayne has unleashed a set of headphones from his ownership. Willingly or otherwise.

Erm, like what?

Sorry I don't write so well. I never have, its been a problem pretty much forever. I suffer from dysgraphia and generally write, read, and edit posts a few times so you guys have a hope of reading them. Sometimes I re-read what I wrote and just say "hunh". Sorry for missing a word. FUUUU that thread is insane in the best way. I understood almost nothing! Posts 19&20 were great. It looks like dude knows a LOT about magnets, but is going to get KILLED when designing the cones. He should team up with someone who makes awesome cones but uses whatever magnets he can get his hands on..... Professional gear is ALL rated to drive 600ohms or lower. This means that you can plug a set of 600ohm headphones into a spare output on almost any studio mixing console. Since pretty much every studio console ever will put out at least 2v you should get enough SPL with most headphones to satisfy even the head-SPL contest holders on head-fi. You could plug a set of 2Kohm headphones in for sure, but they may not go quite loud enough to draw blood. 32ohms is risky - not all consoles will drive 32ohms. The same 600ohm headphones are not likely to hiss when you plug them into that shitty headphone output (a 120ohm resistor tapped off of the speaker amp) on your home stereo. The dedicated headphone amp is a relatively new thing to see in our micro-niche of audio. Why a 120 ohm output? A long long time ago everything on earth used tubes. The majority tube consoles have output transformers. Since studio gear must be able to drive 600ohm loads we usually have an XXXX:600ohm output transformer. Whats the output impedance of that setup? I'l give you a hint... about 120ohms. Maybe 200ohms. VERY rarely less.

I feel like I got the same response the last time I posted a long post from SLC. Maybe just a deja vu of a deja vu from last year.

Hang on, are you speaking from the position of a headphone designer? No, cause you're not one so shut up. None of us to the best of my knowledge are. All any of us are doing is putting off-the-shelf drivers in a new enclosure or taking off the shelf headphones and designing amps around them. We find new sounds with this effort, but nobody here has designed an actual dynamic driver*. The headphone designers have a really hard time of it. Its a wonder they can get anything done with having to work in BOTH electrical and mechanical fields. Let the headphone designers do their own thing, their job is already hard enough. Lack of science? You are out of your fucking mind Straight up insane insulting headphone MFRs like that. The technology in the AKG "varimotion" drivers and how AKG solved the problems they set out to solve is amazing. The ring radiators senn is pushing are a freakish show of knowledge. Beyer is too busy hyping the retarded field strengths in the T1 drivers to talk about anything else, but what kind of shade-tree engineering went into just getting those magnets & coils set up? Ooh, yea, none. They use plenty of scientific methods even when you don't like the results. The additional effort required to design an amplifier around a headphone with unusual (based on what standards?) drive requirements is a joke. There are tons of amp designers on this board. Ask really quick how hard it is to make a headphone amp with 120ohms output impedance. Don't let them weasel their way out with the bitch response of "why would you want to" just ask how hard is it? The effort is nominal. Sorry. *Apologies to anyone who has actually designed a dynamic driver. If you think your job is easy enough to let amp designers tell you what to do I have a few things I could add.

not at all. Put a switch on the front dsavitsk/Donald North/Pete Millet style. Or use separate jacks like Jan Meier does. With a SS or transformer coupled amp its not hard or significantly more expensive to accommodate many headphone "drive styles" with one amp. How do you know its not the other way around? How do you know that its not EASIER for the headphone designers to design around a 120ohm output impedance, and they compromise their designs so that they don't sound like abject crap from 0-ohm outputs? If/when DIYers/Objectivists drop the preconceived notion of how a headphone should be run the people designing the most complicated part of the system (the headphone) will have free reign to do their best. Let the headphone designers steer the ship.

Happy Birthday Todd!

High output impedance FTMFW. If 5.3Kohms is right for STAX, why cant 120 ohms be right for Sennheiser?

Happy Birthday!

Whats wrong with APS-c in this sort of camera? 15 years ago we had full frame cameras that size and nobody complained.

seen on flickr homepage. I am supremely disappointed to learn that you don't own a lighsaber.

Sorry I didnt think of it before: Walmart. http://www.petapixel.com/2012/04/11/get-120-film-developed-on-the-cheap-at-walmart/

Happy Birthday Mike!

Happy Birthday!

Happy Birthday CJ!

I personally lean towards Matrix metering. Its much better at guessing what you want. After that, dial in some exposure compensation to get the people where you want them. Nobody agrees with me, but loosing the sky to blank whiteness isnt that big of a sin. Certainly not as bad as underexposed people in people pictures.

I have been looking for a Konica Wai-Wai ultrawide angle disposeable camera for a few months. It has an 18mm, full frame, plastic lens. But 18mm!!! I want to take the lens out and put it in my Leica. I Just got an email from someone who found a stash of them in their freezer... So excited. http://moominsean.bl...wai.html http://www.toycamera...konica-wai-wai/ http://www.lomograph...sposable-camera I bought 2. One to keep stock, one to hack up. +1 Bright sunlight is surprisingly hard. What do you mean "exposure was all over the place"? The biggest advantage I see with FF sensors today is with ultrawideangle lenses. If your not interested in stuff wider than ~24mm (about 16mm on crop) I don't think it matters that much. APS-c sensors still get plenty of Bokeh when you shoot that way.

Happy Birthday Justin!

Happy Birthday Scott!

@dinny: flash, lots and lots of flash. With a little more flash, in case you dont have enough. Water Droplet by Lord Nikon 12, on Flickr ^^ One image.
