I need a portable amp/dac similar to the Fiio E11 so it can drive my Ultrasone Pro 900's. I wanna truely hear some of that powerful almost over the top bass everyone who reviews the Ultrasone Pro 900's go on about.

Will the Pha-1 be enough for this? I will be using my Xperia Z. Is the Pha-1 only a Dac and won't be able to give me what I require from my Ultrasones?

Any suggestions or answers will be appreciated. Sorry for being a noobie

The pha-1 is not only a dac but also an amp.
I can't really help you with what you should pair with the Xperia Z; I do have the same phone... but battery life and having to reopen and close the flaps made me decide to get a dedicated DAP .
