I can't see half the pix you guys are posting because I am at work with certain pix blocked. I am curious now. Will take the PM-x measurement on the "free-air" foam coupler on my V1 rig.

FWIW, Han's measurement so far seems to reflect closest to what I hear.

Alex, if you don't mind, I just wanted to clarify a little. (And correct me if I am wrong.)

Alex's measurement rig and his measurement techniques are proprietary. That is why he didn't answer you directly about his rig and technique. His mods are also proprietary, being a commercial product.

I believe Alex's measurement rig and techniques are a very big part of his "secret sauce" to getting the mods done as well as he has.

  Thanks a lot Darin for your comment.
 FWIW I have tried around 30-50 different measurement rig implementations and at some point went through something very similar to measurements from Hans but soon realized that HF peak they all show just isn't there, it has to be a resonance coming from the combination of the materials/components used for those measurements. Look at his posted FR graphs, they all exhibit the same peak around 10K, sorry but this in my own view just isn't the reality. Went through the open cell at some point of course but coupling properties are just not there so upper mids were always affected.

So you are saying your shit don't stink and you like the smell of your own farts.

Oh yeah, no doubt my method is prone to showing upper treble peaks, usually around 10KHz, and often a dip right before that. There are occasional exceptions. Whether or not I actually hear them as such subjectively is variable, but anything that stands out in that area probably stands out subjectively (i.e. if it's relatively in line with everything else, good chance it's not something you'll hear subjectively).

  Have nothing against measurements from Hans, Marv, Ultra etc. and you all know my view, it's only valid when they are judged against other measurements from the same rig. Now, whose measurements are closer to reality is another story and it's up to you to decide for your self whose shit smells better so you can stick to it and finally become a happy individual.

I've only experimented with three or four major methods for measuring, not 50. But here is the V1 old style measurement of the PM-X. R channel.

UPDATE: reposted. dammit you a-holes.

   I never offered to take my measurements to anyone for any set except my own. Moreover I take every chance to skip on providing my own measurements of anything rather then my own set when possible (Ultra posted his measurements of one of my sets half a year ago, then Marv posted his, and then it was Hans).
   I then posted mine to give people a view on how things are done here and why I make my sets sound the way they do. Like I already mentioned somewhere earlier in this tread every one Audio Zenith PM-2 will come with comparison frequency response graph, my graph, not from someone else. I actually feel obligated to do so, unlike so many other companies.
   This headphone measurement business is way too much of a commitment that I am not willing to make even if I personally think mine are superior and I do, otherwise why even start this whole modification business? But don't ever ask me to measure your own set, will not happen!

I suppose that's why you started off by using all the data from Ultrabike's rig for your use. I don't think it's quite fair to rely so much on the help and transparency of others and then tout your 'superiority' in a rather closed and absolute fashion.

Fact is Stalin also had squads who job it was to shoot retreating soldiers, no need to hide the truth of the matter. They aren't the first to do so and not the last. As for the Battle of Brest Litewski, I'm not sure you can use that as an example of defending Mother Russia since it was in POLAND! Unless you are saying Poland is like the Crimea and belongs to Russia.

On the heroism of the Russian people. Yes, they performed heroically. So did the French, Brits, Americans, Canadians Chinese and even the Germans and Japanese among others. Your grandfather wasn't the only one ever to fight in a war and you weren't the only one ever subject to "extra scrutiny". It's nice that you are here and hopefully having a better life, but you aren't the only one. This country is made up of immigrants with horrible stories from horrible places, don't think for a second your story is unique.
