When plugged into a Combo Front, why it sounds better when the 1/4 Out is set to "line" instead of "amp"?

When using a pod HD500X into a guitar combo amp, I should set the 1/4 Out switch to "amp" right? 

 

I did it, but when I set it to "line" I  got more volume and it sounds better overall, is that normal?

 

Here is a recording I did to show the difference: https://soundcloud.com/bluesoverdrive/guitar-podhd500x-amp-and-line?in=bluesoverdrive/sets/hd500-test

When you use the Line level it is going to be a bit more output than with the Amp setting.  If you use Line you can overdrive the inputs of the Amplifier, which is sort of like use a guitar with hotter pickup or using a boost pedal with very low boost setting. Listening to your clip the second one is slightly distored and bit louder which would make sense to me. If you like the "Line" setting better with your amp then use it though. Nothing wrong with it as long as the sound is what you want.

I think you are absolutely right! Thanks for the help!
