Hi, that's a really generous offer you make for me to have your headphones for a while, but I don't really want to be responsible for their well-being sending them off to Canada, and it won't really have an important impact on any channel matching or other EQ I'd do for you, at least any changes away from the Harman Curve I'd make wouldn't necessarily be transferable over to you because we all hear headphones in a somewhat different way due to our different HRTF's, most of my changes I make are in the bass on headphones like rolling away the bass from the Harman Curve at around 35Hz which I think helps in bass & overall clarity in dynamic driver headphones but with planars (my HE4XX) they can stand boosting to the Harman Curve all the way down to 20Hz with no ill effects, so there wouldn't really be any personalisation I'd be adding to your planar Closed X anyway.An update on the measurement journey... Oratory confirmed his process. I agreed and I'm now waiting for the shipping address. If I get it by Monday, I will ship it out then. He said he measures HPs every other weekend, so it should take around three weeks. I will ask him in our next conversation for channel balance/imbalance and distortion measurements to help us get some consensus on everything. The idea of having a set of headphones that have been individually measured and EQ'd is pretty bloody sweet. Can't wait.
Robbo, you said you were in the UK, if memory serves me. Do you want me to have Oratory ship the cans to you after he's done so you can play around with them for a couple of weeks?
As an added aside re personalisation, I think I may have found a new preferred headphone target for myself (for the time being at least!), my favourite has mostly been for the 2018 Harman Curve, which is the target Amir / Oratory use as their main target for their published results, but recently I decided to experiment with the baseline flat in-room headphone measurement from Harman which they used as the basis for the Harman Curve upon which they gave people in their study the bass & treble controls to manipulate the baseline measurement to their own preference - which ultimately is how the Harman Curves were created - so I was pretending I was one of their test subjects if you like, I describe it at this post:
Mentioning this because I get the impression you're interested in this kind of stuff and you have tweaked your headphone slightly away from the Harman Target in the past, so you could try a similar experiment for yourself. I have tweaked the target slightly since that post I linked by just adding an additional 105Hz 1dB Low Shelf to it, following is the room curve I applied to the flat baseline measurement and the resultant target I ended up at, which is actually very close to the 2013 Harman Curve (note there are also 2015 & 2018 Harman Curves with the 2018 Harman Curve being one most often used now by Amir/Oratory/etc). Also find a pic comparing the different Harman Curves over the years so you can see how they compare.
HBK Headphone Measurement Talks from Head-Fi and Sean Olive
How is that different from the paper I presented at the HBK Seminar? I essentially took measurements of headphones that had been evaluated subjectively and measured on the GRAS45CA MOD (which you call JBL Modified) and measured the same headphones on a B&K 5128 to derive a target curve for...

I hope Amir takes you up on this, would be great to have him review & measure this headphone.
