@dhart86 Thank you for your post. Your comparison of the Gustard U26 to the Gaia will be helpful to many. I had some initial difficulty playing DSD files via I2S on the Gustard. After some chat with ChatGPT and an adjustment in JRiver the U26 and DA006 talked to each other without a problem. PCM was easy. (The configuration that worked for both PCM and DSD was mode 3 and flag14 on the U26 and AAAAB and IIS-H data set to IIS32bit on the 006.) DSD played natively through the Lumin U2 streamer and through dop to the U26 to the 006 via HDMI.
Just curious, how many hours did you break-in the U26 before you felt the sound stabilized? I have noticed some gradual improvement after about 125 hours.
