Strange one this but I have observed over the last couple of nights a difference in my system caused by using different plug sockets.

I have two double silver plated sockets, the one double socket is a spur running off the other socket.

When I plug my system in and use both sockets it does not sound as good as it does when it is plugged into just the one double socket. I run a power amp off the one side of the socket and the other has a block connector plugged in from which I run a pre amp and turntable.

I am sure there should be no difference but I hear it - strange or what:
