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

If you have a speaker that drops down to 2.5 ohms, with an 8 foot speaker cable, going from 18awg to 10awg will increase the level, at that impedance valley, 0.3db, and the damping will go from 24 to 150. Audible? Maybe.  If your speaker only drops to 4 ohms, those numbers are 0.2db and 40 to 250. Audible? Probably not. Those impedance valleys almost always happen at bass frequencies. This is a change from 18awg to 10awg, so a pretty severe change. Small gauge changes will have smaller differences.

How many watts or amps you are pushing out it not the relevant metric. The lowest impedance of your speaker is, though lower impedance means more amps at the same voltage.

Never heard of Zavfino before today, and I see many mentioning it. A company with USA in their name, apparently based out of little farmhouse in the middle of no where in Canada, and made somewhere in the world. Definitely leveraging the power of the internet and outsourcing.

@sworksone ,

I’m not sure what you have against farmers or Nova Scotia but I have a feeling you might have difficulty finding it on a map.

You may want to think long and hard on that statement. How did I know it was a little farmhouse in the middle of no where, unless I found it on a map? Not sure where farmer's came into the conversation. Do you go the the local farm for your audio cables? I go there for eggs. Wonderful people. They have an eclectic range of chickens. A box of 12 eggs looks like an easter basket, no paint required.

Sorry @sworksone , but if the company was from Iowa, they still would be in a little farmhouse in the middle of no where, and then you wouldn't have needed to be offended, but alas, they are not from Iowa, they are from Nova Scotia. Aren't you supposed to direct your anger at Quebec or Ontario or something?
