Hifiberry Digi+ Pro - HW mods anybody?

[Vhond]

I could only find Hifiberry DAC+ Pro - HW mods anybody? but this topic is almost all of the time about the DAC part of this audiocard.

I was wandering if people had some experience in making the Digi+ Pro (non-DAC version) better?

For instance, better isolation from data and electronic signals like using an isolator board mod??
