Using Fiio E10k Olympus 2 next to Saffire 6 USB?

[Ezeik]

Hi there, I recently bought the Fiio 10EK And found out that i wasen't able to use it at the same time i had my Saffire 6 usb plugged in.
I use my Saffire 6 USB for my Supreeme CU-1 Microphone, but i do not want to plug in my Dt770's into it aswell, since it doesn't deliver as good sound quality as the headphone amp.
I was just wondering if there are any way to use them both at the same time beside each other, or if i have to connect my Headphone amp to the saffire, and if so, how do i do it?
 
Thanks alot in advance, been struggeling with this for a couple of days.
 
Audio Interface: Focusrite Saffire 6 USB
Headphone amp: Fiio E10k Olympus 2
Headphones Beyerdynamic DT770 Pro 80 Ohm

Well, I don't think the Fiio E10K has an analog Input, and thus you can not use it's amplifier stage separately.
I guess, you'll have to pick a Fiio E11K/A3 instead.
(Or E07K/E17/Q1 these are DAC/Amps just as the E10K but I think they all come with an analog input)
