Some is good, then more is better?

I have a lot of Morrow, in IC's seems significant but in SC not so much, seems counter-intuitive but is so for me.

More money than less is always better for manufacturer true.

"Anyway their entry level speaker cables use "X" amount of wire, then as you move up the product line they use 2X, 4X ... Well my question is other than the slight decrease in resistance, what are you getting to justify the jump in price?"

There's a lot more too it than that. The design itself has to be considered. Things like how pure the metal is, how complex the cable is internally, quality of termination, etc., all play a role. A good example is Tara. They use rectangular solid core conductors. That's not something you can buy in bulk. They actually have to make those conductors in house. Nordost is another one. Its not easy to make those flat cables. JPS uses an aluminium alloy. That has to be made by hand, as well.

"Some of these companies put in customer testimonials that state significant improvements. It's the same thing, only more of it."

You have to look at that on a case by case basis. Sometimes the high price is justified and sometimes its not.
