Hi, a question do you connect the amplifier GDN to enclosure Earth grounding ? (for safety and shielding) or do you only connect the earth grounding to the enclosure and keep the amplifier GND isolated from that ? And does that then provide enough shielding (and electrical safety) ?
Looking for experiences, what is the exact rule and is the electrical rule for safety impacting noise coming from Earth connected to the amplifier GND ?
Stay safe, Thx

Regarding safety: your product has to be "double insulated" to not require a PE connection to any metal parts of the product that can be touched during usage.
If you have a mains earth connection it would be very wise to follow Bruno Putzeys' grounding bible (from an audio perspective):
