The greatest advantage of switched sockets to me is that to configure DSP's I don't have to perform body contortions to use the speaker on/off switch and a button on the remote at the same time. This is difficult for a less than agile "grumpy old git". In my case it is easier to use the switched wall socket and the remote in harmony.
