I am using iPhone 5s, and ideally, I hope not to bring a separate player. So, my first criteria is to have something with excellent shielding. I tried a Fiio e11k and it has static noise.
About headphone, I will use IEM (Westone 3 and UE Fi 10) on the street and Senn 650 at home. So, ideally, I want a portable amp. But I am ok with something not so portable, like the JDS O2, but I still prefer something with a battery so I can move around at home.
I am also thinking if I should get a DAC + amp. But the choice is limited with iPhone. Is there a big difference with a DAC? I feel the DAC in iPhone is not bad.
So, I am considering either the following:
O2 amp only. Then I will use it at home with the 650 only.
CD5 with DAC which is portable and work with iPhone, and I can both use it at home and outside.
The CD5 option is more flexible, but will Is it good to drive the sennheiser 650?
Is there any other iOS compatible DAC + amp? My budget is around $400 USD.
