Hey guys, wondering if there are any other portable DAC/amp units out there that are like the Fiio E18 and Oppo HA-2 in that they are intended for use specifically with smartphones? I'm interested in getting a unit that works via USB OTG with my smartphone as a DAC but can also charge the phone. I'm trying to decide between the E18 and the pricier HA-2 and am interested in what other options might be on the market.
Thanks!
Thanks!
