@zlone Innuos has both USB and Ethernet outputs but not S/PDIF.
I have found the Ethernet output to be superior from my Innuos Statement Nextgen. Using a relatively inexpensive Sonore UltraRendu to convert Ethernet to USB to feed my Lampizator GG3 with USB was better than direct USB from the Statement.
Further, using an Antipodes S20 reclocker to convert the UltraRendu's USB to S/PFID to the GG3 is better still.
I recently replaced the UltraRendu with a SignatureRendu SE and Sonore OpticalModule to feed the Antipodes S20 and then feed S/PDIF to the GG3. The gains in coherence and fluidity are almost matched by the reduction in "Noise". Its just spooky good.
My takeaways are in my system USB is not the best output from my streamer and not the best input for my DAC.
Before the GG3 I had a Denafrips Terminator Plus and found using the Denafrips Iris DDC actually improved the USB from the Statement. At the time I thought it was because the Denafrips TP preferred the I2S input but now I think the Statements USB output is not as good as it is reputed to be.
I also had a Yggdrasil and thought the Denafrips TP was in every way, and and among other things the TP had way more and cleaner bass, it made the Yggy seem lean. I have 2 REL S510 subs so my system goes low and is sensitive to muddy bass. The Denafrips did OK on the bass but is no where close to the Lampizator in quality or quantity.
In my experience bass quality and quantity can vary a lot between DACs.
