My primary intention was to see if the I2S input of the DS sounds better than the USB or AES input. So I got this little device Gustard U12 which basically is a USB converter with AES/I2S output. I am observing strange behavior when connecting the DS over I2S
In Jriver, if I set output as 2 x Dop/Native, the interface seems to work fine.
For PCM, there is a small icon that shows up on the DS screen at the top left below the settings icon (this icon is not seen when changing the Jriver output to Dop/Native as described above). The stereo channels seems to be reversed, presents a weird soundstage and highs are rolled off. It plays perfectly fine when connected over AES/EBU.
In both the cases, 192Khz bitperfect test fails over I2S (but works fine over AES). I have tested both the I2S input and both works the same way. My initial thought was maybe the I2S signals over HDMI interface is not compatible but then it doesn’t justify when playing using DoP/Native.
Any thoughts ?
Thanks in advance.
