I have ripped .dsf files from SACD's in my JRiver version 25 library. I plan to hook my iMac to a Marantz HD-DAC1 Headphone Amplifier via USB and playback using JRiver. Is there anything I need to do to get these files to play back properly? The bitrate is huge (5644 to 16934). Will JRiver or the Marantz play them with that amount of quality? Thanks for your help!
