Hey iFi! Thank you chiming in and also for letting me know that you also have a product that solves the same issue.
I thought the issue had to do with USB because the noise went away completely once I unplugged the USB cable from my DAC (the other end goes to my PC) that's why I tried various USB filters. I was really surprised the RCA isolator was able to fix the noise.

You had a ground loop in-between your components somewhere it seems. Of iFi products you listed, none would address it, and iDefender3.0 breaks ground loops on USB lines specifically. Of our range Groundhod is the one that would most likely do it for you, but it's good to know that you were able to solve the problem and now can enjoy clean background
