8. The sample rate supported by K7

The highest sample rate supported

USB: 384kHz/32bit, DSD256

Coaxial: 192kHz/24bit

Optical: up to 96kHz/24bit

The reason for only support up to 384kHz/DSD256 in USB mode:

During developing the K7, we found that there will be noise when decoding some DSD512 and 768k music files. We did try to fix this problem via different methods but failed still. Currently, the amount of DSD512 and 768k files are still limited. So we did not add the DSD512 and 768k support in the K7 finally.
