Qudelix disappeared. It will be hard to trust the kickstarter campaign if it happens.
There is no good reason to not respond to questions this many weeks. I got burned by Kickstarter campaigns before. How can we believe what they promised till now?
1. They haven't even started the kickstarter, none has paid any money for this yet.

2. They already got a good track record with the ES100

Just be patient, I'm sure we'll hear from Qudelix soon enough, I can manage fine with my BT3 in the meantime. 
Checking a site once a day to answer questions.. hell even once a week shouldn't be an issue... but more than a month? I don't think so. I wanted quidelix-5k but now I question... this kinds of silence going to happen after funding campaign? I got burned before...
I apologize for keeping you waiting so long.
The good news is that we finally confirm the chassis design and just started making chassis mold for mass production. Assuming its size and complexity, we expect it would take 6~7 weeks to get the final plastic injection.
We had already ordered QCC512x chipsets last year, and we'll get them by the end of this month.
Meanwhile, we're checking and checking PCBA repeatedly to find any hidden issue, if any.
There are many challenging issues and hurdles for this project. It's the first QCC512x application, and we also need to develop the LDAC by our selves for the QCC target. We're figuring them out step by step, but it takes time.
The primary reason why we opened this project public earlier was to get your feedback and to build the HW specification together. And surely, we believe we had the most of your input when designing the HW.
Anyway, as mentioned above, we've ordered the main parts of the HW and chassis molding, which means we'll start the mass production sooner or later.
For now, at the moment, we keep focusing on development.
We won't let you down. Please give us some more time.
Thank you!

Good! Just don't let the LDAC development keep you from releasing it earlier! I don't mind if we get many of those features as a FW update. 
Thank you for the update! Please keep us posted or else we fear the worst :(
