There is only one sane choice, Kimber Kable. You will have to be very patient if you want to terminate them by yourself. You have to strip up to 48 Teflon insulated wires for each cable, 96 for both. The 12TC is 8 gauge when you add up all the wire. Speakers are current driven devices. The best wires are the shortest you can fit with the largest gauge you can afford. The Kimber is special because of it's extremely low inductance. I do believe it is the lowest on the market. Everything else is marketing and sometimes it gets pretty silly. The advantage of making them yourself is that you can custom fit them to be as short as possible. This is one of the main advantages of mono amps right next to or behind the loudspeakers. There are thousands of speaker terminations. As long as they are well made and secure it makes absolutely no difference. I prefer locking banana plugs. I also solder all connections.
Many people wind up choosing the best looking wires. I'm old school. All wires are ugly and all of them should be hidden. I even hide the amplifiers, all five of them. They are on a shelf directly below the speakers up against the ceiling in the work shop. All of them are balanced.
