@rfagon interesting comment.
Yes, I read in several places that the AES sound is more natural than the USB. Although, it could be DAC dependant also as seen in the review below.

With my Rockna, I prefer AES over i2s, and i2s over USB. i2s has sweeter highs and tighter punchier low end, but AES has a more natural and layered sound and better textured bass. USB sounded quite sharp up top but also felt kind of a "flat" presentation.
I have all three (i2s, aes, usb) hooked up to my Rockna so I can do comparisons or swap connections when I feel like it.
But with the Holo May, I prefer USB over the rest.
The AES sampling rate is on par with Coaxial and less than USB/I2s. Wouldn’t the lower sampling rate be an issue for you?
Any experience with the I2s?
