N-set, I do not think that we from America would be able to talk about 3-phase or to share any 3-phase experiences. We in US do not have 3-phase in residential neighborhood, in fact it is prohibited by code and if you want to have it then it is very expensive to bring in. I personally did not hear audio people experiment with 3-phase.

I do not think that you want any 3-phase; there is truly no use for it in audio. You want one phase but here is the trick question: which of 3 phases you want? Each of 3 phases would have different load, different noise level and I am sure would sound different. Unfortunately you need to have all phases in your listening room (or basement) in order to figure out which one is better sonically.

In US we have 240V supplies throughout and as the voltage brought in it down transformed to 120V. So, we have effectively 2 lines of 120V of the same phase. Those 2 lines of 120V do act in a way like individual phases and they have different loads and the character of the load has little impact to another half. I said little impact but not “no impact”. I would say that 5% impact… The irony and in a way the sad truth is that each of those 120V live do sound very distinctly different. I do not know if it has to do with the way hoe the poll transformer is winded, which line is nosiest, or what is closer to the primary but it always, regardless of the load, one side sound distinctly better then another side. The difference is in a way remind the difference in acoustic absolute phase but in my view it is even more profound. In my listening room the dedicated line has actuals two runs: 120A and 120B, or each of the 240V half. I have just two well-marked outlets…

All of this has very little to do with you and your 3-phase situation might be very different. I think you need to talk more with audio guys in your county to get consult with them.
