1. getting a new rio karma. supposed to have excellent features, eq, sound, etc.

2. Beyerdynamic DT 880 headhones.

Question: Would it sound better/prolong battery life to get a headroom amp(micro) and use it from the dock line out?

 

[philodox]

Yes.

The DT880 sounds much better with an amp.

It can be used unamped with a DAP but it doesn't get loud and will sound duller.
