Not my thing personally, but would you consider making a kit version like other manufacturers? At least for the early adopters could be a nice route and lower the price somewhat.

Although you did not mention it I never expected a sub 1000€ price tag.

That would make it the most expensive piece of gear in my home studio, if you do not count the laptop.

As I said, it certainly seems to tick all the boxes, but hard to justify. I still hope that you can validate the concept and in a couple of years I can grab one for around 500€.

Once again, best of luck on a very interesting if very niche project!
