That sounds really interesting! I surely will look into them now that you mentioned them! I am also quite intrigued by Dunu IEMs as they seem great as well! I know that Sennheiser mentioned that ie800 Dior will have only a cosmetic change, but in my mind, having a cosmetic change will mean that the coating of the IEM housing is different which might change the resonance frequencies of the housing which might result in a slightly different signature and that is something I am really curious about!!
