110 (or 120) vs 220


Hi,

IF an amp can operate at both 110 and 220, and a dedicated circuit is being installed for that amp, is there an advantage to a 220 v circuit? Or is the answer "it depends on the amp"? Or is the answer simply "no"?

basically ,the 220 will flow on more wires creating less restriction . 220 is more efficient ..basically :)
@220 flows on the same number of wires 120v uses one hot and one neutral. 220v uses 2 hot and no neutral. You might be thinking of 3 phase
120 and 220 is single phase

Possibly. At 240 volts half the current is drawn through the wiring and that can result in less power line noise in and out of the amplifier. We pay a lot of money in power cords to do just that. Speaking of which, you can’t use the standard 5-15 (up-up) blade power cord for 240 volts, so a disadvantage may be the cost of a special order audiophile power cord with a 240 volt plug.
