A true dedicated branch circuit does not share a neutral, hot or ground with any other branch circuits.😎

FWIW: Another reason for multiple branch circuits for audio besides dedicated power see my previous post below:

Probably the biggest reason for installing more than one Dedicated Branch Circuit is to decouple the power supplies of audio equipment from one another. Example digital source(s) equipment from analog equipment.
I agree!
That was one of the reasons I ran four 60’ runs of galvanized steel armored MC solid copper core conductor cable 10AWG. That’s four true dedicated branch circuits, one for each mono block amp, one for analog and one for digital. It helps to reduce noise on the AC lines, by reducing the amount of transformers and power supplies on each circuit. Also, the MC helps to reduce hashing noise EMI, and electric fields, on the dedicated branch circuits feeding your audio equipment. You don’t realize how much hashing noise is on the AC lines, until it’s reduced. No ground loop hum. No noise. System is dead quiet with ear against speaker horn, I have tube and SS amps. (The efficiency of my speakers is 2.7% sensitivity 96dB). 😎
