120 or 240 AC current, Which one do you like best?

All of my gear (Linn) can be operated at either 120 or 240
volts. Would like to know which one is better in terms of
noise, voltage drop, stability, etc. I once heard a main frame computer instaler say that noise from a 240 V. outlet was lower due to cancellation from the two hot lines. I have asked several other people on this matter but have gotten all kind of stories.I am in the process of installing dedicated lines, 10 AWG wires with isolated ground. Any help or technical information will be very much apreciated. Thanks.

The main advantage of 230 vs 115 is that smaller size wire is necessary, or longer runs can be made with the same size. Fewer amps must flow for the same wattage of power, because the voltage is higher.

Whether it is 115 or 220 volts, don't attempt it unless you know what you are doing. 115 vac can kill you just as well as 220vac. A 220 volt line is just two 115 volt lines, connected to different phases of the 2-phase power input. Making a 220 volt line is like making a 115 volt line two times. Same skills. Same hazards.
