Tried my Qnktc\Henry Audio Dac that i normaly use with my Hifi systen (vienna acoustics speakers with an xindac 6950 amp). This is an usb dac just as the fiio, but without the build in amp that the e7k have. Connected this to the fiio e9 docking/amp, Wow, what a difference, Tighter bass, more forward vocal, and more treble...or airy/sparklig treble, that i missed in my Fiio e7k. what i did not like was the background noise i get from using the analog input on the e9 amp,so maye i also need a better amp.
The background noise dissapeard when i disconnected the usb connection to the E9 amp (only in use when e7k is docked), so now the background noise is gone :)
