Star Grounding refers to having individual wires connecting PCBAs, devices, and in this case Outlets back to a single place for connecting the grounds together with mains ground, or a dedicated drain wire.

In and of itself, not a bad idea, assuming that the AC is clean, and that there is not a huge RF influence.

But it will not isolate one outlet from another, which I do not think is a good idea for audio anyway...
Happy Listening

Thank you. Sounds like I should just stick with my Power Wedge, as - alaskahiatt 13:06:13 05/15/24 (2)
it does everything you mentioned using isolation, star grounding, RFI filtering, and protection from power surges.

  One thing to remember when talking about protection from Mains Power deviations, be they low or High, addressing surges - abnormally HIGH voltage is simple -
  put a Thermistor in series with the line load-
  
  Addressing Under voltage (aka Brownouts) is more of a challenge w/ out a true 'protection circuit' that will shut off the supply if the incoming voltage is below your set point - 120 VAC... typically involving some sort of sensor/or relay that has a narrow trigger band...
  Happy Listening
  - This takes care of my brownouts nicely...-. - ABliss 19:57:24 05/16/24 (0)
    Highly recommended.
