@sbilotta,…Some simple advice on the road.
Which you can also ask your electrician…or trader,to see if he/she is knowledgeable within this with dedicated mains to a music-system.
• You have 3 phases,.ask your electrician to use the phase that has the least electrical load.
• Also ask your electrician to use a phase for your dedicated mains to the music-system…
Where Refrigerator and similar equipment are NOT CONNECTED.
• That your electrician connects your dedicated mains cable to the music-system,.so close to the incoming main cable in the “fuse-cabinet” (it’s called something else in the UK) as possible.
• Ask around which cable sounds best,.it is sound quality differences even on cables for dedicated mains.
This lacks many,many traders,.as well as most electricians experience about.
But ask around,.so that you know what to install for cable.
-Richard.Dane does not want that we give advice on good cables here for fixed installation,.this is because of,.that different countries have different regulations.
But someone here on the forum from the UK,.may have tested and can give you a suggestion for a good cable…for the best soundquality for your dedicated mains.
This based on listening tests,.not technical specifications .
Here in Sweden we have tested different cables for dedicated mains,.and there are big differences.
But I have to respect Richard.Dane and be silent about this test-results on the forum.
• Socket without switch,.and of good quality.
Again,.ask around,there can be big differences in soundquality.
I cannot give you any suggestion,.this is because you in the UK have a different kind of contacts.
And it is a pity,.because we have just completed a major test on this with sockets and contacts.
• Ask your electrician to avoid sharp angles,.as he bends your dedicated mains cable.
• Ask your electrician not to tighten the wires so hard,.so that he gets “blood-taste” in his mouth (finds no other way to describe it)…it sounds worse.
• Ask your electrician to keep your dedicated mains cable as isolated as possible from other mains cables,.it sounds better.
• Ask your electrician to connect the cable as it is,.do not use “crimp-sleeves”, “forks” or solder in the cable-end…It sounds worse.
Hope this was right,.can be understood in English.
This above,.is a few simple advice for you how to get the most optimum installation possible.
But remember that it is your electrician who shall perform all of this.
You may be prepared for some to dismiss this advice,.or to laugh at it.
But it’s just out of ignorance,.they haven’t tested,so don’t bother with it.
There are some more little things to keep in mind,.but we’ll stay here at the moment.
Good luck…
