So I'm stuck between either the Hifiman HE-400 vs the Denon D2k on sound quality. Both are within my current price range and if I get the Denon, I'll definitely try getting a Fiio Dac or something more than just my current Fiio E11... But yes I really want your guy's opinion on these two. I really like bass but not overly a bass head. I want the music to be slightly off neutral and more "fun." I just want some opinions on these two based on the following criteria:
Bass
Mids with great male and female vocal clarity that are slightly forward
Airy Trebles
Detail retrieval
Highs that are not harsh
Huge soundstage
