No, but I have gone from USB to AES on both my Yggdrasils after testing it out on one of them
AES gives best quality. USB on Yggdrasil is good, but not compared to USB interface of AudioByte Hydra-Z with Hydra-ZPM (and others like that). AES is the best, then BNC, Coax SPDIF, USB then optical. The difference is not extreme, but the sound with AES gets a bit more focused and clean. Easier to position the different instruments in the room and more details in the instruments.
The owner of Audiobyte and Rockna also recommended me to use AES if I2S was not available as a general rule. I have also done extensive listening while switching between the different inputs. Always end up with the same list (mentioned previously in post).
