Hi,
although I called it simple, it always seems longwinded by the time I get through all the important points.

I'm glad you had the patience to read it through.

The main thing is keep the different grounds separate until the CSG then you have the flexibility to experiment if an obscure problem crops up.

Would anybody have an example schematic for the ground filter networks AndrewT was talking about?

Have a look at this page (scroll down a bit), where I show a schematic of the grounding scheme I used for a chipamp with separate PSU. It is absolutely silent.
