I told @Torq that I am still perfecting our finish - we may fill the grain a little more, although I always love to feel the texture of the wood if organic and natural feeling. The more quartersawn the wood the more banding and chatoyance it has. That set may be just off quarter, slightly rift, still very very nice!
Was up pondering what 300b tubes I should buy for the Glenn 300b I picked up (really which ones? They are all so expensive I have to pick just one set!) and decided to take some measurements since we just finished our first week making production/review sets of the closed Verite. We didn't really make any tweaks to the sound since CanJam London, but I do think that things are going more smoothly and that the FR is totally set so I wanted to post some graphs.
As usual these are taken with our AP system. AECM206>AP1701>AP515 audio analyzer
EDIT: This is Diffuse Field Compensation
Universe Solid Lambskin (dotted) Vs auteur solid Lambskin (solid)
Hypothetically, the auteur hybrid pads with suede on the earside and lambskin on the other parts, should make the bass very close to flat and retain the treble of the auteur pads. Measurements when I get those done soon!

To me - the closed retains the texture and ease of the open Verite, while ofcourse giving isolation, but also being a touch more "alive" as the upper treble is slightly more elevated in that 8 to 10k area. They both come across as very organic sounding, with forward mids and accentuated 3d space, overall the open Verite is a touch more "lush."
The last thing that was holding me up in tuning the closed was making sure that the sense of space and "three-dee-ed-ness" was retained from the open. The 3d space took a lot of airflow, damping, and driver placement changes to get to the final tuning. Ofcourse when I started tuning I thought I could just mimic the driver placement from the open and get the same thing, I was totally wrong! The driver is actually not angled like the open, but the airflow is completely different in where baffle ports and vents are located. Also - the cups are machined to 110mm diameter whereas all our other headphones are machined to 108. I know it may seem like 2mm isn't a lot, but it makes all the difference in a closed headphone.
Excited for everyone to start hearing it in the coming weeks!
I'm glad to see serious care about craftsmanship everytime you make a new design!! The industry needs you!
lol. Hopefully my idea for my Verite C works out,
