Hi Yoshimitsu:
Currently, we don’t have detailed plan for next gen KTB, our audio team did work on a new version KTB with some improvement like:
- Balanced Output
- Add Volume Control Knob
- Case/Housing
The new KTB is same DAC with existing version. In the meantime, our audio team are also trying to resolve Hump issue, we will update more details in the next few weeks.
Thanks for support!
