I've been enjoying using the Fiio E17 for over a year now, and it serves many purposes throughout my listening day. By day, I have it hooked via USB to my PC, then out to my home stereo via the L7 LOD. By night, I use it to listen to music on my ipad with headphones connected to the Fiio E7 through a powered hub.
SO, my question is would there be ANY advantage in terms of sound, if I added the Fiio E09 into the chain? I love the EQ controls of the E17 (which surprised me, because usually in many products thats a very gimmicky ad-on), so I hope I wouldnt have to sacrifice them.
Any insight is more than welcomed.
