What is star earthing (or star grounding)?
-
Are hydra power cables star earthed?
-
Do hydra power cables sound better than individual power cables in Naim systems, and if so, why (other things being equal)?
-
If you get a hydra, what items should you include in the hydra and what not include? Specifically, should you include the power supply of an audio switch in a streaming system?
Star earthing/grounding is more related to amp signal grounds, this brings all the -ve in the signal path to one (common) point - the circuit can be drawn to look like a star, hence the name.
Re your question: Its been adopted with power supply earthing in audio & AV as an improvement over the more common buss bar method. see drawing .
In the electrical world its called a radial connection.
Do the Hyrdra’s have it, I don’t know, but looking at the construction & the connection box, I’d say probably more than likely as it does not make sense not to.
Re Hydra’s, I made my own once, not for me I’m afraid, too untidy.
But my power dist board in use now does have radial (star) L,N & E

My experience of using a Hydra is that it improves upon the standard Naim leads but isn’t as effective as separate Powerlines.
