Speaker Cable-The Best of the Cheap?

One question I have concerning DIY construction, whether the Canare 4s11, or other DIY Cables, do some of you go to the extent of also sheathing the cable?

I've seen some pics of the Canare 4s11 just terminated, and heat shrinked, and it looks good, yet sheathing would add some "boutiqueness" I suppose.

Does anyone have any recommendations on Sheathing, what types are available, what will be the improvements gained, and where can one buy good sheathing, which is also reasonable in cost? Sorry for all the questions, but I suppose one never learns if one doesn't ask!
Thank you! mark

"Just like audio gear, a $1,000 Speaker Cable will no doubt NOT sound 10 times better than a $100 one."

I cringe when I read that argument, which I've even seen in professional reviews. The relationship between price and performance is not linear and who would ever expect it to be? Of course it's all diminshing returns! The question is not whether a $1,000 cable sounds 10 times better than a $100 cable, it is whether it sounds $900 better TO YOU.

Off soapbox, and not meant as a snipe at Markd51.

The soft gray finish of the 4s11 is reasonably attractive and I've never bothered to sheath it but it's certainly a possibility if you want to make the cable less obtrusive by matching a carpet color, for instance, or more obtrusive if you're making some kind of fashion statement.

The brand of sheathing you most often see is Techflex. You can google that and find lots of information and sources. One easy source is Parts Express but there are many others.
