It won't damage the equipment when you plug a device with safety ground cable in a socket without safety ground.
You merely run a risk of getting a firm jolt from such devices when they either have unusually high leakage currents OR when something (a component or wiring) in the device fails in such a way that metal parts you can touch get electrified by specific internal faults.
This is why it is called safety ground.
With SMPS that have a grounded cable this ground usually is ONLY connected to the mains side and NOT on the DC output side.
That is the tricky part.
This is why I suggested to ground the enclosure (bare metal parts of it) or the RCA shield to an actual ground.
That ground could be a groundpin in a wall socket or (all metal) piping of central heating or water piping (when all copper) and then only on bare metal surfaces as paint isolates.
These SHOULD always be connected to safety ground. Unless, of course, some plastic piping is used.
But there is no way to convert an outlet thats not grounded by plugging in a powerboard with grounded connections right? its still not grounded? You have to have it grounded the whole way?
