note:

Different batches are always different

Some internal parts changes (individual capacitors, and Bluetooth modules, these will be a little different for each batch) familiar without notice


Only the cracked version of the driver can play DSD256, if you need firmware, you can send me your email,

Apple system cannot play DSD256, because it is driver-free, only the WIN system with the driver installed can play DSD256




Color Classification:
