AC Dedicated Line

Hello guys
I will run three (3) dedicated AC power lines: one for my stereo system (power amp, preamp, DAC, etc) and two for my stereo subwoofers (one line for each one).

These three circuits will be connected directly to the main AC board of the Electrical Comany wich provides me the service right at my door.

They will all share the same ground cable, wich I will connect to a dedicated ground bar, but I would like your opinion about sharing the "same neutral line" on these circuits. Could it affect the sound quality? 

If I have to send three different neutral cables, one for each circuit, I will need more cable to run through the house and it will be more expensive and complicated.

Please I would appreciate responses with real experiences. I don't want to start a technical discussion. I know at the end, in the main board, they all will share the same neutral line, so electrically it should be the same, but in this crazy audio world who knows for sure if soundwise it will be the same....

PS: by the way, I will run 4 or 6 mm2 cables (I guess about 11 to 9 AWG on the US scale). Here in Argentina we measure cables by square millimitres.

If using dedicated lines and keeping your musical signal pure 
don’t put the surge protection in a box to corrupt line conditioning 
a dedicated unit such as the Siemens is excellent handles med spikes to large 100k surge protection right at the breaker panel 
and uses 2 - 20 amp breakers right after the main breaker 1st in line protects both sides of the buss Siemens First surgeFS100
or 140. Great piece of mind  and 10 year warranty,and led sensing 
and audible alarm if fault detected.
