Longer power cord for Phantom Gold?

[ragwo]

Does it really make a different in sound quality to buy a more expensive power chord?

I was thinking about a standard power chord, but the wire is thinner than the standard one, which comes with the Three White.

My choose are either buy two new 3 meters power chord or a longer power strip with 10/12 trigger, so the standard one (2 meter) can reach the power strip.

In my opinion, buy two three meters cords. That's the safest bet electricity wise and you won't, or at least I didn't, hear any difference. I was quite shocked discovering the standard power cable being just 0.75mm². My bedside table lamp has the same dimensioned power chord.
