I run a 12 gauge "bare" copper line from the system to a copper ground rod that is driven into the ground under the window behind my system, The main, system-end connector and the wire/rod connection are both soldered, and the bare wire is routed to avoid "incidental" grounding before it gets to the ground rod. In my system, I get hum if I try to ground a bleeder to the house ground, which - of course - shares a bus with the neutral wire at the main panel, per typical residential protocol. Even in cases of a "split bus" for neutral and ground, the wires therefrom typically route to the same ground, whether UFER (underground ferrous electric), or (rare in US) a driven ground rod or rods (Code presently requires 2).
While I agree in principle with a dedicated (same pole) circuit for digital/switching gear, in the end, the ground is usually shared, and this may be a problem that needs dealing with, in and of itself. Again, it seems to be a good idea to at least have "home runs" for hi-fi circuits. meaning, all dedicated circuit wires are unbroken between the outlets they serve and the main breaker box.
N-set, I also like a nice, tightly connected, "buttered" fuse in lieu of a magnetic or vacuum breaker for hi-fi circuits; but for most people this feature would be either redundant or a Code violation.
