@audio123 thanks! I enjoyed TWF41 myself, have been using it with my DX90 for well over a month now and is currently my daily driver. I agree that it is warm, I don't find it to be too thick, but I have no experience with thin sounding IEM either, so I can't make a good judgement myself. And my ear definitely isn't trained to hear any coherence issue, but it is a hybird dynamic and planar, so I guess it's expected to some degree.
Happy to know Nova is better in technicality! I have some problem with TWF41 fit, hopefully Nova fit my ear better and can be my daily driver.
