This website uses EMU1616m to measure other DACs:I really would like to see the measurements of your Motherboard, Amir.
I'm using the ALC1220 chip on my MSI Z270 SLI PLUS board to feed my headphone amp because it measures pretty well via RMAA.

It seems that a 7 years old Realtek can beat a Schiit. Amir can measure the ALC1220 without being called a Realtek shill as it is not easy to buy a PC motherboard without a Realtek.
Same 1kHz spaced spikes in Amir's report:
