I'm getting my self a Pandora UMPC, which I plan to use for both portable listening and as a studio in my pocket. After poking around a bit, I've found the specs of the sound system

The internal amp can produce 150mW at 16ohms.
Now, I'm aware that a good headphone amp will increase the sound quality of any portable device. What I'm wondering is if the internal amp is powerful enough to drive, say a pair of beyerdynamics DT770, or even DT880 without necessitating an external amp? Note I'm not asking if it will sound good. Only if it will drive to a good strong level

Forgive me for sounding a bit "noobish", I will admit I'm fairly new to finer audio gear. If the info I've provided is not enough to make a guess, please tell me what more is needed.

Thanks a lot. This site is the greatest

that and straight power does not always mean driving power equals good. there are many manufacturers in the world where headphones dominate who like those in the speaker world, make complimentary stats that don't compare directly to other manufacturers.

I guess the amplification will be the TWL4030?

From my understanding, yes the TWL4030 is the amp.
Hoping the Pandora will face no more delays
