Seems as though the Hermes is doing a fine job of cleaning up the USB signal and converting it to Spdif (AES) for your yggy. I too had the same experience when I used a Matrix X Spdif-2 in between my computer and the yggy. The Pi2AES had a slight advantage over the the X Spdif2 and I used that afterwards and omitted the computer and have never looked back. Fast forward to today and the Lumin has pushed out the Pi2AES when it comes to AES.I do enjoy the unison USB on my Yggy LIM. HOwever, I also have the yggy fed via AES by a Hermes DDC and the ddc w/ aes is wayyyyy more cleaner and grander sounding than the USB. The aes sounds more refined in every frequency. I know the hermes ddc helps a lot but the usb just cant keep up. But the unison usb is lightyears better than standard usb implementation in other dacs.
Please note I do still keep the Pi2AES for my second system.
I did try to use the Matrix X Spdif-2 between the Lumin's USB out and ygg's AES. The matrix was no competition to that of the U1 Mini's onboard AES/EBU output. That experiment lasted all of ten minutes and the matrix has now been sold.
I do how ever suspect that the Lumin has an optimized USB output far superior to that of a standard computer. Im just unsure of the new Unison usb for the yggy which I would need to upgrade in order to satisfy my curiosity.
Which is why I am looking for feedback here.
