Will increasing speaker cable AWG make a difference in sound quality?

I heard Paul of PS Audio swear by 10 gauge once. Now I agree with him even with my efficient Cornwall 4's.

10awg,Its a good place to be <>..."that paul knew a lil somethin".

@thespeakerdude I am in no way angry.  I never get involved in the frequent audiophile forum disputes but I was put off by your comments and felt the need to say something.  I’m not sensitive, but for someone to call an area “middle of no where Canada” which is 15-20 minutes from a town known as “The Hub” of the province I’m from (which is a 45 minute drive from the capital city), by someone I highly doubt has ever been there, was to me offensive.  The fact that you’re not understanding of this after being made aware of it is to me rather telling, and I’ll leave it at that.  Feel free to continue engaging, but I won’t be commenting further.  

Draped in a cloak of secrecy that appears to be showing signs of wear and tear, thedudespeaker. 

At least hint towards the very fact you’ve been to Niagara Falls ….
