Old post but I am searching for solutions at the moment. This is what i am doing right now with a voodoo lab ISO-5. Temple audio board with power module on the side. I'm just searching for another power supply that is not as tall (the ISO sticks out just a bit on the bottom when I set it down). Having an extra IEC plug for the FM3 would be ideal but I'm not really finding anything outside of voodoo lab which puts me back to the same height issue.i was also thinking about Y cable (IEC). One end goes to the power outlet and the other end splits into two : FM3 and One Spot. Anyone tried that?
