Extension cable question

[Daniel Weston]

Hi guys
I have a hi-fi set up in my second lounge comrpising of NAD amp, cdp and tuner. I've repositioned the stand and needed a 5m vs a 3m extension cable. I purchased a standard 5m Yodata one from Builders but I notice that the thickness of the extension cable is thinner than the 3m one. Does this have any impact on my setup or should I be looking to rather run a 'heavy duty' extension?
Cheers
