Maybe you miss the bass in the HD203 i think. The Hd 439 have good bass but not elevated bass. The sound signature of HD439 is relaxed but you can do the bass mod. A FiiO E06 is powerful enough, but a e07k is ideal. I had a HD203 and for me, buy the hd439 was a major upgrade, the refinement, the detail, vocals and mids. However like i said before you can do the bass mod. Here is a link.
