Amen to that (and im not even relegious) 
My 5K+ has misalligned optics and cracks and so on.
i’ll hack it (the 5K+) once I recieve my first 8K X

Funnily enough I do believe in the misaligned optics my left lens had terrible light bleed. No cracks after 1 year + though.

and that estimate comes from a dismantled 5k+ (if you remember these pictures)
where did you got these ? PLEASE QUOTE THAT PART SO I CAN SEE
your way to keep things on a professional level?
I like how everyone already made up their minds about the X.
FFS Just wait like 2 or 3 more days and someone will post their impressions of the final unit and it won’t be a paid review.

It seems tomorrow the first backers will receive theirs

Yep. Just wait for someone to get theirs and let’s ACTUALLY find out if the ACTUAL unit is good or terrible.

Wow that G2 resolution looks so good! It’s too bad HP didn’t just use base stations for tracking and allow us to use our Index controllers.

No, I was just referring to the demo 8kx Seb has vs. this G2, in terms of colours and so on.
Every time Pimax give an answer on the production 8KX as to what has changed, nothing has changed that could really affect the optics to a large degree.
I was told on several occasions that my model has the final panel and changes would only be made that affect audio and mechanical parts. Therefore I believe optics of my model are the same with the ones that are now sent out. Of course I would be happy to be able to review a final unit with the final audio solution in place though.

Yes, a full review of a unit with the final audio, new automated lens alignment approach (during fabrication), new face cushion, eye tracking and Pimax Experience with IPD wizard in place would be interesting!
It might make sense to reserve at least one fully validated device that can be sent to reviewers. Optimally when everything mentioned above is in place for a polished production unit experience of what people who would order an 8kX could expect to get.
Imho a bundle with DMAS and eye-tracking could be offered right away by Pimax (perhaps even as the only option) as this is imho the experience that people who spend money in the region of an 8kX would likely be after. If this would be the bundle sold, that could also be the thing to be sent to reviewers. With Index and now G2 the “Deluxe” audio option is now pretty much the standard in the $600 upwards class to compete with.

A pre-production model doesn’t have the finalized Quality Control which checks the tolerances of the fitting (lenses, panels, etc). Also, you don’t have the final distortion profile - so you experienced distortion. These are usually shipped in the release version, if we look at Pimax’ history of handling Firmware so far. The difference between sn203 5K+ from June 2019 to sn204 5K+ from October 2019 was drastic - I had both.
So your optics and panels are not the final version, because they may or may not be misaligned, unfortunately.
It’s a pre-production model. They usually did not go not through the final QC. They had 4 months indoors to screw around with distortion profiles, software, and to set up the process en detail for quality control.
P.S. I think you guys need to send Sebastian the final version btw.

Yes, but the distortion profiles will be updated by pitool, so my unit also receives those optimizations.

I second that! 
I believe they will, so I can show the improved audio and all. Of course, loaner would be totally fine.

On PiTool and profiles: May be true, yes. I just want to draw attention to the Vive Pro, which had automatic factory calibration set within the FW for each individual unit. It was the reason people were always told to export and save their profile when doing the lens mod, as that would be irrecoverable if overwritten by a lens mod distortion profile. Honestly though, I don’t know whether Pimax has adopted such a process too. I’d conclude most manufacturers would do that, as it’s the best route. But, don’t know.
On release unit: They should send you the final unit, so you don’t have to do a handstand everytime and say pre-production unit. It’s in their own interest as well.

The distortion profiles do get updated by PiTool. When the pre-production unit arrived, it was basically unusable because of an older PiTool version that was installed on my computer. Then the distortion profile was improved in the newer versions of PiTool. Same was true for the 5k Plus, distortions got improved over time.

That means they need tight tight tolerances during assembly. If one shoe should fit all.
HTC calibrates each profile individually after assembly, part of production. Probably reason why they stuck to the lenses going from VivePro -> Cosmos. Production-realities, or large stock of lenses. It’s interesting to explore why they’d do that.
After having tested the LensMod in the Cosmos Elite, I just don’t get HTC’s decision though. It’s easily a much clearer and better picture than my Index and 5K+ had. Would say best of gen 1.5

Yes, I’m still not completely convinced that manufacturing tolerances aren’t one factor in the different perception of distortions. I mean, we didn’t get a single thoughroughly positive user feedback from the people who were able to test Sebastian’s 8kX (before the lockdown) either. Sure, it wasn’t a double blind test, but I don’t think Sebastian had any deliberate influcence here.
And it would also explain why the Artisan was perceived so much better, even when using the same FoV and the believable statement that there shouldn’t be any technical reason for that - same display angles, same lenses etc.
Perhaps it might make sense for both @mixedrealityTV and Pimax @PimaxQuorra to come up with a solution where Sebastian sends back his 8kX prototype for analysis in the Pimax labs in exchange for a production unit? That would be really interesting and maybe helpful - understanding whether something is wrong with the fine-adjustment of that unit. And if yes to review the new auto-adjustment process to check whether something like that could still happen or not.

So… Will you buy it?

Just like I wrote in my preview, people who have never had problems with the distortions in the Pimax headsets will also not have any problems with the 8K X.
For the 8K X unit I have here, it has just the same kind of distortions like the production 8K Plus that I received. If for some reason now the final units are totally different, which I don’t think because only audio and mechanical parts have been changed, I’d be glad to check one of those out.
Another factor why I probably perceive less distortions in the Artisan, next to the smaller FOV, might as well be the higher refresh rate. In the Artisan, the lens correction gets applied 120 times per second while in the 8K X only 75 times. That makes a difference.

Ok, the 8k+ was at least already aligned with the new automated process as far as I understood, so this might be an indication that this alone doesn’t solve the issue. It’s still the old cushion, not sure how much impact that has.
Don’t completely get the part with the higher frequency, at least without eye tracking and dynamic distortion correction. If I e.g. turn the head with constant speed and have two HMDs, one with twice the frequency than the other, wouldn’t the images that were calculated by both headsets (every other one for the fast HMD) look identical in both content and distortion? (The faster fps one would just calculate more in-between images).
But perhaps it’s not manufacturing tolerances and analyzing this headset wouldn’t help. Having a look at it couldn’t hurt though (also not for you, if you get a new one that way 
). Sure, the many praising reviews from the roadshows could be highly curated and many of the people there could already have been used to these lenses. Still, if even a minority would have hated the experience we’d have heard of at least some of those here in the forums I think. But no idea, really. We’ll get a lot of feedback from a manifold of people in a few weeks anyways
