Dedicated AC lines form star grounds. In the PS Audio Music Room we have multiple grounded AC receptacles on dedicated lines. That means that each AC receptacle has its own wires running back to the central breaker box where the main ground is also located. If each piece of gear is plugged into its own dedicated outlet, then you’ve formed a star ground.

Star grounding is a sufficient but maybe not a necessary condition. using star grounding is one possible way to guarantee that you won't have hum. Another is to spend enough time messing with an amp to find where every wire and ground goes so that the hum-causing currents do not happen to flow where they
Grounding and Shielding for your DIY Audio Projects

Absolutely avoid having any ground conductor handling both signal and power returns. Avoid multiple ground paths for the signal (ground loops). Use only one end of the shield inside equipment. Do not connect the chassis directly to the signal or power supply grounds. Isolate it with a type X2 capacitor and parallel resistor.

connect all signal grounds (RCA plate terminal) to one common point, choice one power unit's ground as common ground.the common may be a wire,a track on a pcb, assemblied the power units as compact as possible. P.S. when do air wring,use strong wire or big copper as common ground.

Amplifiers - Grounding. When two or more devices are connected to a common ground through different paths, ground path noise, or a ground loop can occur. A potential difference between these two grounds can cause unwanted noise voltage in the circuit paths. Currents flow through these multiple paths and develop voltages which can cause damage, noise or 50Hz/60Hz …

One of the sure methods to reduce hum and hiss pickup is to attach a 3(three) core audio shielded cable or 2 no.,s of 2(two) core audio shielded wire for stereo audio amplifier input. The two core wires carry the audio signal while the shielding only after getting connected to mains ground directly, will shield the signal from external hum and hiss noise(50Hz-60Hz).

The connection to the power amplifiers system ground The preamp star ground - at the phono connectors The preamp section also contains digital circuits. The digital ground needs to connect to the preamp audio ground, and this is done on the main preamp PCB as it needs to be near the PGA2310 chips to avoid issues.
