In short, the answer to your question is "yes."
Of course the "necessary" gauge of the power cord is related to the required current draw, thatÂ’s why 30 amp circuits require a larger minimum sized wire (10awg) than 15 amp circuits (14awg).
My amps each have 8A fuses and I run them off individual 20A circuits. I use power cords made with 11awg wire and they sound great.
The other stuff is subjective and you can read here for hours about gauge, silver vs. copper, stranded vs. solid, shielded vs. unshielded, geometry, EMI, RFI, ferrites, connectors, conditioners, etc., etc.
My experience is that power cords do affect the sound of components but how each manufacturer accomplishes that, and whether the effect is positive or negative is still subjective to the listener and their specific system. There are a few power cord manufacturers whose products have a somewhat "universal" appeal and you can read about them on these forums. LessLoss and Isoclean are two that come to mind. Oyaide connectors are well regarded (but not necessarily their cords), and also Furutech connectors. At the lower to mid price range, Elizabeth would say Pangea Audio offers good sounding cords (I have never heard them) and others would say try the DIY offerings from VH Audio. My best advice is to either use appropriate sized generic cords and don't worry about it, or to listen to a variety of cords (borrow and trade from your friends or dealer) and decide for yourself what you like.
