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 …

Grounding an audio amplifier - correct signal references. Grounding is a catch-all label for a number of different topics, which IMHO is confusing. The topics are: Current routing (especially power currents, e.g. power supply or speaker connection); Correct signal reference points (a.k.a. "signal grounds").
Grounding System In Power Amplifiers - AUDIO WORKSHOP

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).
From grounding to audio amplifiers - Electrical ...

The LM386 is somewhat unique among ICs because its inputs have a resistor-to-ground built in. Imagine a 50k resistor from pin 3 to pin 4, connected inside the chip. There's one from pin 2 to ground also, but in this circuit that's moot because pin 2 is grounded.
How to practice best grounding – PS Audio
https://www.psaudio.com/ps-how/how-to-practice-best-grounding/
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.
Amplifier Grounding - Tubelab
http://tubelab.com/safety/amplifier-grounding/
The proper grounding scheme of a vacuum tube amplifier has been the subject of many debates, blogs, forums, and web pages. There are actually two important aspects related to proper grounding, hum reduction, and safety. The safety aspect is often overlooked, or ignored in the quest to eliminate hum. With careful design it is possible to satisfy both criteria simultaneously.
Grounding and Shielding for your DIY Audio Projects
http://diyaudioprojects.com/Technical/Grounding-Shielding/
Since both the signal ground and tone arm ground are connected at the phonograph they will form a ground loop (between the shields and ground wire) when connected to the amplifier. The solution in such cases is to separate the grounds at the phonograph.
