Heyo. I joined the drop a few days ago. I currently am sporting a Fiio E07K. I plan to get an L7 cable and a Schiit Vali in the future possibly, but I don't have too too much funds at the moment. How much practicality vs functionality do you think there is on upgrading to a Fiio E07K and Schiit Vali via L7 from just a Fiio E07K?
