Tyll will be putting up all the graphs soon. No idea where yet. Could even be my server as its not for profit.
-
Copyrighted info... will get the permission to share... They are pdf's... As soon as i get permission i will post the links.

I got newer graphs from tyll/audeze and at least they don't show the rise to infinity at 5khz. I commented over there too. If you think i'm dumping on these headphones then you clearly do not understand. I will be getting a pair. I will customize the open loop version of the dynafet if necessary to maintain as flat a frequency response as possible. They are definitely better than the he5/6. I want to nail down where these inconsistencies are coming from, it could be the software tyll is using. But we will surely get to the bottom of this. I'll be doing my own testing once i get them. On my own equipment which is different from tyll's. Closest thing to a stax diaphram yet. My krell preamp has a phase button, and absolutely i can tell. Classical music on speakers, it is instantly noticeable, one is clearly right and the other is not. The switches on the hp1's are exactly phase switches.
-
Sure seems like people over there are mis-interpreting my comments. Lots of people can detect differences in absolute phase. Tyll's graphs clearly show that the absolute phase was 180 degrees out. That is both channels were wired opposite of every other headphone he tested. Not one channel out of phase with the other channel.

I like the Lou Malnates better, there is one of each within about 2 miles of my house. Life is a bitch. Next year maybe one of the all you can eat sushi places. And oodles of sake.
-
I showed tyll's photo above to one of the women i work with. All she said was poor choice of shoes.
-
We got to get people to use decent stax jacks. Otherwise it looks kickass.

I have a business partner that was formerly in the optometry business. I (as recently as 2 months ago) tried every single one of the multi-focal contacts. Boy do they suck. In the morning driving, every stoplight turns into 6 pointed stars. Lasic is a very bad idea. After 10 years (especially when you are older) it drifts badly, and is then not correctable. DON'T DO IT.
-
If you are near-sighted, when you hit about 45 you won't be able to wear contacts anymore. You will see what i mean when you get there. All current solutions stink.
-
If any of you that have bought and taken delivery of the boards decide that this is a bit much for you then please sell them (at no profit) to someone who desperately wants them, and let me know who you sent them to. Although i would love to end up with a couple of spare chassis (for the SRX) the idea was 19 boards sets, and 19 chassis sets.
-
L brackets i can make in infinite quantities. 4 of them 6 feet long only weigh about 25 lbs. Its a stock item, not custom, so no minimum. Same thing with the stax jacks and the tops and bottoms.
-
I'm assuming you mean the profile you are showing. You gonna drill and tap all the holes? Your arm is going to get tired.

Its the flame thrower burned volcanic ash icelandic edition Yes those were srx3 pro's. Probably close to 30 years old. Owned by mypasswordis For those of you that have seen the sony 5400, the finish is absolutely identical to that. And its a very deep anodize. Which means that the screws fit kind of tight the first time. (waiting for a swt61 comment...)

http://gilmore.chem.northwestern.edu/staxprod1.jpg http://gilmore.chem.northwestern.edu/staxprod2.jpg And off to spritzer shortly. If there is a second run of boards, we can certainly change things at that time. No way am i doing another 700 lbs of aluminum.

The heatsinks are 16.2 inches long and 2.95 high. Don't remember the width. Would have loved vertical fin cast heatsinks, but the prices were just stupidly high.
-
Not true. Jude definitely knows what reks looks like. Last year every time reks came into a room, jude quickly left. You mean Cuddly Dudley... (most of you people outside of chicago will not understand this but it fits reks perfect)
-
Wait a minute, something is seriously wrong with jude... He was even friendly to me, something i thought would never happen, and now this with reks... On the other hand, now with 20k$ or more rolling in the door per month, maybe jude will lighten up a bit. NO WAY?

I'm going to chime in and say that i really appreciate the tolerance of alternate everything here. As a jew growing up in a 99.9% christian town, i got to learn first hand about religious intolerance, its just as bad as racial intolerance, sexual intolerance etc. In fact working at a university the tolerance of intolerance is absolutely frowned upon. In fact any violations of religious, sexual orientation, marital status, citizenship status, racial status (and two more i can't remember) is cause for dismissal even for tenured faculty. This from a school that 50 years ago would not allow jews to attend. I sure wish things were more tolerant when i was growing up. And i think its great that married couples are actively looking for gay positive churches. This is definitely new. So i'm tired of the filth that rush limbaugh and the morons at fox news spew, and i'm very tired of the people that listen to and bow down and pray to these jackasses. It certainly includes the gays in the military thing. Keep up the good work.

Heat rises. Would probably be a very good idea to make longer umbilical cords and put them next to each other, or on different shelves. That is on my list of things to do. But those things take so long to make... Higher voltage at the same current is higher power. P=V*A its not just a good idea, its the law. BHSE=+/-400 volts T2=+/-500 volts
-
Spritzer just admitted to me that he put a passed out AL in the womens bathroom. Just fucking classic. So now we know what happened... Just fucking classic.
-
el34's really don't perform well at 600 volts. 800 volts is better at about 60% power. 1000 volts is even better at about 80% power. After you hear what it is supposed to sound like, you can't listen to a lot of the other amps.
-
OPEN, as in dipole, no damping whatsoever. Same as stax (except for 4070)
-
I am going to throw this out, i said something to tyll but he was not listening. The lcd2's when he tested them were the only headphones he has tested that are 180 degrees out of phase. I very much doubt that this could have caused any errors in the software, but the phase at about 5khz went to infinity because of this. Someone needs to re-wire the things and do it again. I think he was using an aftermarket cable for the measurements, so maybe one more time with the original cable. Still they are great sounding headphones and i'm going to have to get a set as soon as possible.

Corrections... The diy T2 is not the hottest amp on the planet. The original is, by something like an additional 20C. Justin wilsons bottle of booze came from me. The two of them killed it pretty quick. But he was not willing to do another bottle.
