RCA cable for stereo - premium cable any different?

[Wade Preston Shearer]

I know there are some audiophiles on the list (I've appreciated responses I've received in the past about home theater and audio equipment). I need to run some RCA cables 75 feet. 


What's your thoughts on the difference between this one for $7.5:

And this one for $60?

This cable will be in the wall before sheetrock.
