Hello,
 
I was wondering if someone could tell me the sound signature of the Alo Audio Pan Am amplifier, is it a dark sounding bassy amp or a thin sounding amp with extended highs?
 
And what kind of headphone is recommended to use with it, a dark, thin or a neutral sounding can?
 
Also, is it worth getting either the Passport or Getaway external battery packs? Do they improve the sound quality of the amp?
 
Thank You!

And is there a better amp that I can get at the same price?
