I note that in addition to the voltage also the frequency changes,
230-240 V 50 Hz and 110-120 V 60 Hz.
In my humble opinion, the effect of the different frequency must also be considered,
or at least postulated that this difference is considered negligible.
In a rigorous scientific study it should be proven, not in this case
A transformer designed to work optimally at 50Hz also works at 60 and vice versa, of course, but since these are non-macroscopic listening differences,
a 20% frequency difference may not be so negligible.
Thanks in advance to whoever answers me .
100v,115v versus 230v
Some audio technicians/ enthusiasts claiming that, high end audio equipment performs much better european 220/230v even 240 UK voltage if that's the case why USA 110V / 120 volt AC ?

it has been a great discussion, I would love to hear from designers manufacturers if there is noticeable difference better performance running 120V Audio equipment on 230 volt naturally requires step up/down as ditusa has mentioned in his post he is running his gear at 230 volt ,
I run my amps on 230Vac.They sound better. (Improved speed and better transient response.)

glupson6,016 posts @ glupson but I have a few unused ones, too. I have nothing to plug into them (except the tuntable that would then be too far so no need anyway),Just a guess the "unused ones" were installed at the time for "220V" window air conditioners. How does it go in real life? In the U.S.A., I have usual 110V outlets, but I do have a few 220V (240?), too.There is a good chance if you measured the voltage at your 110V outlets it is closer to 120V than 110V. What ever it measures the hot Line 1 to hot Line 2 voltage at the electrical panel will/should measure twice that. Example: Hot Line to neutral, 110V. Hot Line 1 to hot Line 2 will measure 220V. Audio equipment that has dual voltage primary windings power transformer will still output the same secondary winding(s) voltage and exactly the same volt-ampere rating(s). The only thing that could influence the performance of say a power amp would be Voltage drop on the mains if a 120V branch circuit is used verses a 240V branch circuit. Possibly another reason, for here in the US, if 240V mains power is used it basically could be considered balanced power, 120V - 0V - 120V. As for this: stefano_f1 posts @ stefano_f The frequency has nothing to do with whether the voltage is 230-240V or 110-120V. The frequency is determined by the Utility Power Company’s generating plant. https://www.worldstandards.eu/electricity/plug-voltage-by-country/ Jim. |
