All the grounds in the system (input/earth, chassis, PCB) tie together at one point near the power connector. This is standard practice for audio equipment and generally required for compliance with safety and EMI law.
I'm not sure what you're saying about the Naim's requirement, but I've heard a couple strange issues before which were unique to NAIM. Some people use "cheater plugs" to lift a device's ground reference but it's not safe for you or your equipment. It's better to find the root of the issue. Have you encountered an actual problem or are you anticipating one? Can you tell us what the requirement says, verbatim? -- seanadams ------------------------------------------------------------------------ seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=52412 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
