Another case of USB being a dodgy standard. I run my Zenith Mk3 into an Antelope Zodiac Platinum with Rubidium clock. To get it to sound as spectacular as it can it took the following:
-Intona USB 2.0 Isolator with Intona reference cable
-Acoustic Revive REM-8 EMI/RFI suppressor
-Acoustic Revive RGC-24 ground conditioner
-Acoustic Revive RUT-1 Usb filter
-Low latency setting on InnuosOS
-short Meicord ethernet cable from router/switch
-black ravioli/FinalDaruma feet
That said, it now performs at reference level using Ipeng, roon being a distant second for sound quality.
