I have UM Merlins that have been compared to the k3003 a few times as they share a hybrid design and some similar sound characteristics (although it doesn't have 3 filters to choose from), and I am looking for a dynamic IEM that is more balanced across the spectrum. I read that the RE-400 is supposed to be balanced sounding (even though I know you hated it) but everyone says the 600 are a serious upgrade and they add just a bit more sub bass, have sweeter mids and offer a more refined sound and a larger sound stage... everything sounds awesome but the cable issues are holding me back. I don't live in the US/China so a cable replacement for me would be an issue.
the bold parts stand true ,but i don't think it's gonna best your UM Merlin , so don't expect miracles when comparing.
