Need Opinions for Different Cable Manufacturers/Cable Designs

Cables are like woofer coils. It's  copper and how much.  

My suggestion is that you don't spend your hard earned money on any set of cables unless you are able to first try them in your system. Many retailers will allow you to do this if you leave a deposit. Listen to each brand and go with the ones that sound the best to your ears. 

I currently have Kimber, Silversmith Audio FIDELIUM and Micca cables. They each sound a bit different but are well matched to my system. It is good to have a few different pairs handy because over time if your ears get tired of a particular cable, you can quickly change them up. 

The Miccas in particular are interesting because they are $40/pr on Amazon and sound awesome! 

PS, I agree with other comments that you dont need to mortgage your house on speaker cables because the returns will be de minimis. If cables are your thing, better to spend on interconnects because there is a much greater audible difference between low end and high end interconnects. 

Another vote for Cardas. Got the Clear Rev.1 for RCA and it blew me away. Tried some Clear reflection speaker . Not as good as Clear rev1 . Another one is Luna. Not very well known yet. But one of the best ratio price quality . 

Here's one. Get simple, affordable 12AWG OFC wires and you're set for life. That's all you need. Anything on top of that is pure marketing, and in many cases, the 'bells and whistles' some companies add on actually introduce noise. 

Choose science over snake oil, man.
