recently got some ue900s. looking for a decent amp/dac i can use at work, while being portable enough to take home at night.
I have an o2/odac at home. I would probably get another, but looking for something cheaper if possible. if i had more money i would just get the headroom pico amp/dac and call it a day lol.
was thinking fiio e18? can i run this from usb all day?
