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 ?

clearthinker,

I remember a note in the newspaper in Germany, before 2000 for sure, that mentioned intention to go up from 220V to 230V. It said "nothing will change but you may need to change your light bulbs a little more often".

I may be mistaken but I think that whole European Union is 230V at this point.

jea48,

"Unless a piece of equipment, like a monster power amp, consumes more than 1440 volt-amperes continuous power it’s a violation of US electrical safety code to install a 240V branch circuit and receptacle in a US residential dwelling."

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. Granted, they are used for washer, air conditioning, etc., 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), but I did not fully understand your post about "legality" of them even being there.

@ JEA48..Thank’s Jim. One of my mono block amp’s draw’s, 1500 Watt’s @ 230V/6.Amp’s,@ 8ohm. ( Per your space, heater example.) GREAT...The wall plug is a leviton ( 5842-I.) Amp cord is a NEMA 6-20p to C-13 power cord,15A/250V 14/3 AWG 1ft long...

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 .
