I will be buying a portable amp exclusively used with my portable players (Cowon J3, D2, X9).
The thing is, I'm still about to audition some full-sized headgear and some of them need an amp for better volume/sound (as I've read from the forums).
The only available amps in my place are Fiio, Audinst, T-box, and BAB1-Xa.
As for Fiio, E11 seems to be the candidate for my use. But it seems a lot of people recommend E17 or E07 because of DAC. I won't be connecting my future headgear to a computer.
I chose E11 because of its changeable battery. 10 hours won't be good enough for my usage (hence the players with good battery life) as I usually stay out of electricity for 2 days or so. But also, the big plus is the price.
But will I be missing anything else from E17 apart from use of DAC?
Fiio E07 has some competition with regards to price. T-box has a longer battery life and Audinst is on par with price too.
And as for E17, its price also contends to Bab1-xa which has a battery life of 300hrs (according to the company brochure... which I think is overstated).
My question still stands: Will I be missing anything else from Fiio E17 apart from the use of DAC?
If it matters, the candidates of cans I'm about to audition are:
Beyerdynamic DT770 PRO 250Ohms
AKG Tiesto K176
