I've heard everyone talk about using the digital input (lighting connector/30 pin connecter) for apps like JamUp sounds much better than using a headphone adapter (like the one from positive grid). Here's my question - how big of a difference is it really? Any advantages besides higher audio quality? My concern is if I wanted to use my phone for live shows and using the digital adapter i couldn't plug in a power source if i needed to (not that i would but one thing to consider)
TL;DR - is using a digital adapter instead of the headphone adapter for JamUp or other apps really worth it or does it really make that big of a difference?
