Do you mean 14/16 mm or 14 *GAUGE*? Most wire size is given in gauge, and the lower the number, the bigger the cable. So 14 ga. would have less resistance (and possibly more bass depending on a lot of other factors) than 16 ga.
What are you willing to spend on cable? There are some speaker cables specifically made for tube amps from Transparent and Audio Magic, but they're pricy.
Otherwise, I'd just get some Audioquest GBC on closeout here. You'd be hard-pressed to get better for anywhere near that money.
