We regret to inform you that there was an error in the description of the changes described in the recently issued release note on the latest firmware for the NT-505 and NT-505-X.

The description of TIDAL connect was with regard to the UD-701N, not NT-505/NT-505-X. However, we are working on the development of the NT-505/NT-505-X firmware to be compatible with TIDAL connect.

We apologize for any inconvenience this may cause, and appreciate your patience and understanding.

Please visit the below link for the detail.
