North American 120 volt vs. 240 volt
My power amps have a voltage-converter cube on the back. I can change between 120 volt and 240 volt operation by removing, turning, and reinstalling the cube...and changing line fuses and power-cord ends. Simple 'n' easy.
The circuit-breaker panel in the new house is full. I like the idea of increasing the power-amp operating voltage because I'm going to have to run a sub-panel to my listening room, and new wiring and outlets within the listening room anyway; and if the voltage doubles the current required will be half--which potentially saves on the cost of copper wiring. My previous amp wiring in the old house was dedicated circuits to each amp, 15 amp breakers and 10-gauge wire from breaker panel to the outlet. I'm thinking that I'll need half as many power-amp circuits for the new room, if the voltage is doubled.
All the sources will stay at 120 volts--preamp/processor, CD player, etc. Depending on how the system is finally configured, I anticipate balanced XLR cables from 120-volt preamp to 240-volt power amp, but ordinary RCA interconnects from sources to the pre/pro.
Any downsides I haven't thought of? Ground loop issues?
