I had a couple of grand worth of equipment in two connected rooms blown out last summer by a lightning strike, so I value what Bob is saying. But would having the equipment turned off at the time (some was, but most was on) made any difference? It traveled between rooms over my remote speaker cables. I think I would have had to have physically unplugged everything to avoid what happened.

As far as the OP's question, most of my equipment is on as I mentioned, connected to the mains through some protected Furman power strips. The computer, router and modem are on a UPS. I have some things like speakers and the printer on one Furman that gets switched off when I leave the room, but the computer and my hardware synth and mixer stay on. [The firewire connection is too flaky to work every time I power up, so I just leave it on.] My ammeter says 1.4 amps most of the time, so I'm not much worse than a couple of light bulbs worth. In fact, since I replaced all the incandescent bulbs in my house with LEDs, overall I'm ahead.
