grounding

[yulquen]

Silly question,

but when putting say a D/A + power supply in a metal cabinet with power supply, is it advisable to connect digital or analogue
ground to the cabinet, through direct wire or cap,
or not at all?

if youre using an IEC power inlet, do you earth the cabinet
the same way ? or is 2 wire inlets more common in the
digital audio world ?

at least on pcs the cabinet is both earthed and connected to
dc ground, but thats a different (noisier) area.

Thanks in advance.
