Thanks for your reply. I’m running Roon Core on Windows 10 professional, 64 bit version, latest version of Roon (1.3?) My PC is hooked directly up to my DAC via USB 3.0 connection on back of my PC. My PC is Gigabyte board with an I7, 8 Gig of RAM. Data/files are stored on a NAS - Buffalo 4 tb mirrored disks, no performance issues with all other files/mounts that I have.
I don’t have screen shots of the audio setting in Roon, but can tell you that I chose defaults for DSD, no conversion to PCM, no default filters. using USB driver from Bryston.
If this is not enough let me know. My one additional item is the DSD audio file worked ok in JRIver, downgrading it to PCM, but I haven’t tried as a direct DSD file. I’m willing and want to do another test with a recommended DSD file.
Let me know.
