I just got rid of my Denon Dk7s and got a set of MrSpeakers Mad Dog w/Dog Pads. I tested them out using my FiiO E9/E7 combo -- they're pretty good, but I have the feeling they're distorting at significantly lower levels than maybe they should be. I've been using Spotify Premium with and without Audio Hijack Pro EQ settings (mainly the 10-band EQ settings below testing with Gain levels lower than pictured, around 30%).
I'm wondering whether my FiiO combo just isn't powerful enough to push these 'phones. Is the combo close or way out of the ballpark?
I tried to search for anything related to what I'm looking for, but I just couldn't find anything comprehensive. Apologies if this is redundant to something else our there.
