Need to purchase a speaker cable to connect my head to my cab which is about 30 ft away. I've noticed a price difference in the Livewire cables for the 14 gauge and the 16 gauge, the 14 gauge being more expensive. What's the difference between the two and should that play a factor in which one I buy?

16 gauge is fine.
More than large enough for a 30 watt amp.
Even at that length.
For a larger watt amp (50+) I would be inclined to go with the 14 at that length.

I have 18 gauge, about 10 feet for my AC30.
Been using that for years with no issues.

The longer you go, the thicker the cable should be.

If you are running 4ohms, you need to go with the 14ga. The lower the ohms the thicker the wire as well. 16ga would be okay with 8 or 16 ohms cabs.

At a couple of feet it wouldn't really matter, but @30ft it will.

Yeah, you're right there.
Although the Peavey Classic 30 does 8 and 16 ohms.

Damn, you're like my conscience, stating details that I forget to mention
Maybe I need to get more sleep. God knows I don't get enough as it is.

It's all to do with resistance of the cable - if your impedance settings are 8 Ohms amp and speaker, and the resistance of the cable is 2 Ohms, then it's not a great percentage of the total, but if your system is using 4 Ohm speakers, then the extra 2 Ohms is an appreciable proportion of the circuit - and the cable just dissipates the electrical energy as heat, wasting it. Thicker cables have less loss - which is always the case.
