@WooAudio I've some concerns about the USB C implementation you decided to do. Based on what I have seen, you are shipping the unit with a special USB C to USB C cable, and a regular USB C to USB C cable doesn't seem to work (based on experiences of persons with the unit). I looked up the USB C specification and there are only 2 types of USB C to USB C cables that are allowed (Section 3.4 defines them), so section 3.4.1 and 3.4.2 define USB C 3.1 and USB C 2.0 respectively as the only two allowed by the specification and none of them have directionality, contrary to that the cable you are shipping with the unit is a "OTG" cable that has a host side. Based on that your cable doesn't meet the "USB Type-C Cable and Connector Specification" and it's going to be a pain to find replacements.
Is there a good reason for you creating your own cable instead of adhering to the specification?
I've not received any additional communication regarding the WA11 after I pre-ordered it in July 2018.
The main advantage of USB C is the compatibility, if at the end the WA11 is only compatible with your special cables and your special charger then there’s no sense on using USB C. It’s like having proprietary connectors because we don’t have options other than buying the cables from you.The USB-C input for DAC and for Charge on WA11 was carefully thought through AND tested extensively. We know that USB 2.0 has plenty of bandwidth to pass Hi-Res Audio including DSD so the 10Gbps bandwidth of USB 3.1 Gen 1 is not necessary for music playback. Additionally, we seperated the power delivery on WA11 so the sound quality is not impacted when the battery is charging while in use.
It would be easy for us to implement the USB 3.1 Gen 1 standard if WA11 ONLY needs to be compatible with the latest devices that also complies to the USB 3.1 Gen 1 standard. The reality is.... there are many computers, tablets, phones, and DAPs with variations of operating systems and USB controllers our customers are currently using. In our extensive testing with a wide range of devices, it was clear to us that the implementation of USB from big hardware manufacturers (Microsoft, Apple, Google, Samsung, Lenovo, Dell, Sony, etc.) varies GREATLY. Think about how cumbersome to use an Apple device with Lightning port (Apple Lightning to USB "camera adapter" required) with an external DAC/amp today.
In the end, we needed to pick our battles so we chose compatibility without the need for adapter and dongles as the primary objective. The supplied USB-C cable is a specialty cable (directional and OTG). This ensures ONE cable will rule them all. If we use the USB 3.1 Gen 1 standard, some WA11 users will have to use an adapter with their devices that don't meet the USB 3.1 Gen 1 standards. In the near future, customers will be able to buy replacement USB-C cable on our website and on Amazon with Prime shipping.
Pls. send an email to info@wooaudio.com with your order number and a team member will check the status of your order.

It's not part of the USB type C specification.It is not a proprietary cable although it is not widely used.
That's good, does it work with USB type C chargers or only USB type A chargers? As far as I understand it needs to meet certain requirements for a PD charger to recognize it as a legacy device and supply 5V. What happens if someone uses the supplied USB C to USB C cable in a PD charger to try to charge the WA11?you can use any USB 5V charger
