IMO....
If you're biggest concern is the "Thinness" of a component cable, then you're in big trouble.
As it relates to HT cables/speaker wires, you'll find a correlation to "Thinness" and cheaply made garbage.
How much space to you expect to save by purchasing thin wires..... 1/16th of an inch? Thinner component cables translates into a smaller gauge and inferior shielding.
