5M power cable from fuse box to HiFi

The fuse box in our villa is in my HiFi room, so I am considering drawing a dedicated line from a dedicated fuse directly from the fuse box to my power amps. The needed length would be about 4 meters (I will probably make the cable 5 meters). The cable will be "in the room" and not inside the walls.

My power amps are NCore NC500 which are known to be sensitive to the quality of power, but which bulk power cable would be best?

I live in Europe, so a requirement is that the cable can be ordered from here. 

As I see it, I can either buy a power cable in bulk (the easy option) or try to make my own. I have OCC copper in everything else so I will go with OCC copper this time as well (no silver plating, yuack!).

Some options for bulk cables:

Or I could make one myself, by using awg 12 OCC solid copper from Neotech for line and neutral (ground can be any cheap cable), but due to the length removing insulation will be problematic and it would have to be a simple twisted geometry and no shield.

Any suggestions?

Yes, 220v, 3 wires (hot, neutral, ground)

I have a Transparent PIXL power conditioner (bought it used) which made a very noticeable improvement, so I have a feeling the power cord used will also matter, although the biggest improvement will probably come from using a dedicated fuse (no back noise from computers etc).

Dedicated wires may not make much difference.  You either get enough power during transients or you don't.  Like I mentioned, the power is coming in dirty to having a really high quality wire to preserve the dirty waveform doesn't help.  I'm not familiar with your power conditioner but it sounds like it is working for you.  

I'm not sure what european country uses a neutral wire.  I bought a european amp and it expects to see 240V+, 0V, and then a ground for protection only. 

Unless you have 4 wires, 2 hot, 1 neutral, 1 ground, I would suspect you have the 3 wire configuration I described above. 

BTW, the dirty power I'm describing at my home is supplied to my amp by a dedicated 10 awg 240V circuit.  Not sure it makes much difference but I know for sure I'm not short of power to my amp.

Cleaning up dirty power is the job of the power conditioner, the job of a good cable is to not decrease the quality of the power (signal) and prevent other nearby cables from getting noise from it.

With a perfect amplifier, or a perfect power conditioner, it should not matter, but previous tests at least in my system show that it does matter quite a lot.

Do you know the three things we often talk about for speaker cables: resistance, inductance, and capacitance? They all matter for power cables as well.
