Native DSD files in DSF and DFF formats are supported by the BDP-10x series players (BDP-103, BDP-103D and BDP-105) with firmware version BDP10X-50-0422. Customers who purchased the players prior to the summer of 2013 may need to perform a free firmware update before the player can recognize DSF and DFF music files.
