All my files (DSD, PCM downloads and CD-rips from BOT-1) are stored on my external 2 TB USB solid state drive, played via BDP-2 to BDA-3. Created three folders, labeled DSD, WAV, and CD-RIP (All my HiRez downloads are in WAV format). I play the DSD files via my Wireworld Platinum USB cable, and my High Rez PCM and CD rips via AES/EBU (which I prefer over USB for these PCM files). Also feed HDMI from my Oppo-103 to play SACD DSD.
