Default Running an amplifier unearthed

Well, it depends on what else you have connected to it I suppose. You would
need to find out in this case why it says it has to be earthed, If its just
hum and buzz and pick up of rubbish then its safe but if it has large
capacitors between the earth and live etc, then you will get quite a belt.
I guess that if they are specifying an earth they probably have a reason
for running it that way, but I doubt if its going to be in danger of the
mains shorting to the earth, that would be silly. Its mainly appliances
which may be in the vicinity of water or which have components that might
fail like powerful motors that need an earth. Fridges Washing machines,
Vacuums etc.
I never did quite get why garden equipment has no earth though.

If you read uk.d-i-y, you may have seen a thread ("This appliance must
be earthed") about Dutch mains sockets, which are often unearthed.

If I plug a Cyrus 1 amplifier (which has an extremely metal case and a
stern label saying "This appliance must be earthed") into an unearthed
socket, do I risk death by electrocution, or worse, poorer sound
quality?
