With my Surfans F28, if I attach a portable DAC to it, the bass sounds washed out and the vocals have less clarity. How do I fix this?

OK. I see what could possibly be the problem. My Surfans F28 DAP already has two DAC chips hardware inside. So I am guessing that if I try to add a outside DAC, it'll interfere with the built-in chips? Thanks!
