Hi everyone, I have owned 20$ Creative EP-630 IEM for a while, and I now upgraded to 50$ Fischer Audio Consonance IEM. I am a bit disappointed in terms of how much of a jump there was in audio quality (however I did notice more sub bass of course and ever so slightly clearer trebles. This is with 320kbps MP3, and a Dell XPS 14 laptop (no USB DAC). Now I am wondering, if stepping up to the DUNU DN1000 IEM will 'let me down' again in terms of the audio quality jump from the Consonance? Because in a multi IEM review, the difference between the EP630 and the Consonance is far larger than the difference between the Consonance and the DN 1000. Thank you for your tips/ advice/ recommendation. (By the way, if you were wondering, I do have good hearing).
