Hi. A 14awg wire is good for 1800 watts max. Keeping 80% for safety is 1440 watts.
I’m in EU world at 220V
Hi again, I’m not sure of your amount, 2.600 watts or 2 pieces rated at 600 each, I’m not thinking straight tonight 
15 A x 220 V = 3300 W 80% = 2600 W for each of my 5 dedicated socket (each one with dedicated wires phase neutral and ground).

People oversize wire, less resistance and can hear a difference because of that, I wish my hearing was still that good, I don’t know what 4sqmm wire size converted is, I’m bad at converting metric and I don’t have my code book here to look it up in the tables of sizes.

The chart above is for size but I cannot find a chart able to take into account also the difference for 220V vs 120V
If I’m understanding what you’re after correctly, each hot line of 220v would stay within the amperage rating of the conductor: it doesn’t double up because you have 2 phases: 3300watts divided by 220 = 15 amps, per hot line: you would need to up a wire size; 12 gauge for 20 amp rating

So now you would be within the 80% rating of the conductor at 20amp
I discussed with the electrician and we have decided to go for stranded (no solid core used and available here) 4 sq. mm wires that is close to 11AWG. The Furutech outlets are rated for 16A with 220V and each circuit breaker (differential) on the main dedicated panel is Class A. We will use also larger conduits for every dedicated line (3 separate wires each = phase + neutral + ground) or max 2 lines together (6 wires each). Maximum length of 10 meters each. Soon I will have 5 dedicated lines, 5 circuit breakers, 5 single NCF rhodium plated outlets, 1 dedicated main panel for audiophile stuff only.

Excellent,
Luca, if you have no choice but to use stranded, please try to at least twist or the three conductors. More work, but it will help.
Solid conductors are not available in the EU?

Thank you Tony, as per my (trusted and experienced) electrician solid core wires aren’t usually used in domestic circuits (almost here in Italy) and he is firmly convinced our final decision above mentioned is the right compromise according to my components needs, code compliance and general safety aspects.
I already have used 1 dedicated line since 2 years, it has 2,5 sq. mm wires at 16A-220V. Just one common (non audiophile) outlet with a P20 feeding my entire system, amplifiers and subs included.
It always worked fine and it makes me presume how my future plans can improve from this point on.
If any other EU or Italian member on this forum has more experiences to share with us, will be very appreciated.

A bunch of acoustic treatments have been also removed.
Here a more clear view of what I’m fighting:
a window door on the right wall
an empty door way on the opposite left wall
The 20th March is much closer day after day, can’t wait! So anxious to finally have the room perfectly symmetrical rebuilt.

It’s coming alone great!

My now naked room sounds really awful: boomy and fatiguing, with voices that seem coming from a tunnel! Never thought each treatment or stuff collected along the months could make that kind of difference on sound.
It’s a well know and predictable aspect, I know, but when you can experiment with your ears can’t imagine how the room could play a role, maybe the most important in this hobby I’m afraid.
I need to be patient for a while… sobh!
You need headphones…

Headphones are key to marital harmony in our home. I use them at least two hours every evening. My wife goes to be much earlier then I do.
