More to the point: why should it matter if you have a floating ground? Earthing the chassis helps (though is not essential to) pass EMC and safety tests, but there need be no other connection between signal ground and Earth.
Thinking about it: most of my components don't have an earth connection at all - they use 2 pin mains cables and plugs. Certainly I could easily put together a source component, amp & speakers and have no earth. Needless to say, they work fine. No hum. (Well, apart from my subwoofer - but that IS earthed, so I think the hum is from a ground loop). It still sounds to me, though, as though the Naim amp is relying on signal ground and chassis ground being the same thing at some point, but for some reason, they're not. -- AndyC_772 ------------------------------------------------------------------------ AndyC_772's Profile: http://forums.slimdevices.com/member.php?userid=10472 View this thread: http://forums.slimdevices.com/showthread.php?t=33414 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
