Snarl,

I think your friend is mistaken. 8-) Let's look at it another way.

You start with 10 apples and you split them up into two groups of 5 apples. You give 5 of those apples to your friend who tells you he then splits them again into 3 apples and 2 apples and it tastes just like ten. He's still only got 5 apples to work with. 8-)

Also, every time you introduce another physical connection into the signal path, you're increasing resistance.

Cheers,
