If the goal is to eliminate noise fed back to the mains then the best solution seems to me to remove all connection from the digital devices to the power mains. Just run them off of battery power. This is practical for DACs as well (i.e. separate battery power from computer).
If this approach is inconvenient it is at least available as a useful testing tool when exploring how noise makes it to the analog audio gear.
