I'm using a fiio e17 currently and I'm loving it's basic EQ/Tone control.
For convinience reasons I want a proper desktop amp
which I'm going to connect with my hifi main system.
My first thought was to buy the fiio e09 and dock the fiio e17 onto it.
This way I would connect the fiio e17 via spdif with my home cinema receiver.
so I can still use the fiio as a DAC with its EQ.
Though this setup is kinda bulky with the spdif connection being on top of the e17.
Are there any other good headphone amps which offer tone control?
