I guess every situation is different. I have found circumstances where people say stranded wire is better for their speakers. Personally, I prefer thin gauge, solid core wire. I find solid core less irritating than stranded. Multiple runs of it to achieve the desired awg. I found Axon's 20 gauge high purity to be as good as I came across. The price is a mere fraction of what Kimber and AudioQuest charge. I used to buy it for a little over 5 cents/foot. I cannot imagine it being more than a quarter/foot even today. I would say it is a mirror of AudioQuest, and sonically better(to my ears) than Kimber. I originally twisted the wire, then went to braiding(didn't notice MUCH difference). I found 15 to 17 awg to work well for tweeters, 12 to 15 for midrange drivers, and 10 to 13 for mid-woofers/woofers. I would also steer you toward HomeGrown Audio for wire. They have both solid core silver and copper. Their wire is 99.999% pure, solid core, and teflon insulated. The copper is $0.39/foot(maybe available at a discount in quantity), the silver is $2.80/foot($1.80/ft for 50+ feet).
