Thanks Steve,
Glad to be able to wrap that up.
Coudn't have wished for a more conclusive answer.
Cheers!

No, it just costs more money to use thicker wire. Many audiophiles (and Bryston power amp owners!) use heavier gauge cords in the 7AWG to 12AWG range (which would be equivalent to using 10AWG to 15AWG or 5.26mm² to 1.65mm² for you 230VAC users).
Technically larger wire has less resistance and therefore less voltage drop across it, but it's kind of negligible when dealing with short lengths like 1m - 3m. I don't personally spend a lot of money on power cords, but I do usually use larger gauge wire than necessary, because what the heck?
