Can you line out with the galaxy 5?  Which amp is best to listen with an ATH-m50?  E5? Also, do any Amps have dual output for 2 people listening simultaneously?   Thanks!     Wasn't going to go with amp route since I'm looking for portability, but just considering my options.

Would PowerAMP app be decent sounding on a 5.0 player?

Out of the DT770 Pro, ATH-m50, and the Ultrasone HFi 780, which one(s) do NOT require an amp to push the bass and sound overall right out of the box?  I listen to mostly hip hop, alternative/rock, remixes.  I want to be as portable as can be for 18 hr overseas flights and traveling.  I'm not an...

Oh ok, I was afraid that was going to be the answer.  What other alternatives do you have aside from Voodoo?

Is it because of the Android version on stock?  What if it is rooted?

Yea, I don't plan on doing the amp connection right now.  I just want something portable and not clunky for gym use and for when I travel abroad.    

Thanks man!  I'm leaning towards the Galaxy cuz I like the features plus the ability to offload my apps, games (seldom play), and music listening to the Galaxy and not my phone.  But, I wish the 5 had some of the 4.2's features.  Hmm.  There's no such thing as perfect.   4.2 or 5?  What do...

Anyone?

I'm looking at both of these DAPs as an alternative to an ipod.  I definitely would like an Android device as I already own an Android phone and am very familiar with the OS.  Also, my phone's battery and SQ definitely pale in comparison.  What I'm looking for advice on is the SQ, battery life...
