What I have is modded 1Z and Romi 1Z with BG caps. For me, most of my iems are warm such as EE phantom, SE5U, CA Andromeda and JVC FX850 just to name few. I hate cold sounding, clinical iems so that’s to that. And I listen to vocals, acoustic, jazz. My mod 1Z is a cross between regular 1A and 1Z. So maybe the comparison is not fair.
But what I want to say is this. I think using the right firmware is very important. My absolute fav firmware is Cerberus mix with1A/1Z+ with Gear of War flawed upgrade version. It has the best clarity, resolution, etc etc compared to other firmwares. It clears up Phantom thick, syrupy, haze and replace with naturalness. How should I say this ~ it sounds like a very natural EE Zeus with amazing timbre, smacking bass etc. is it a good match? Definitely, it’s no longer warm, syrupy thick iem but become a natural timbre, clear, cutting iem but not clinical, like a perfect Zeus.I use CN region, since has best clarity, resolution of all region. In its place, the thickness of Phantom is cut down a huge portion by the choice of firmware, region, use of cables and mod. It’s kinda like doing EQ, I’m not sure if you notice, but when EQing, it’s better to cut down/ reduce frequencies, rather than add more. It’s kinda the same principle.
Phantom can be a very good match with 1Z, since technically it already have strong basic foundations of good timbre, bass. So you just need to reduce haze, thickness, increase clarity and resolution by choice of firmware, cable, and region. My goal is to get the most natural sounding music, where it’s like you are there in the venue, listening to live music. It can work, Romi modded 1Z is definitely the best modded 1Z I have heard in terms of naturalness. Best bass, extremely immersive, like hey I’m there listening to the singer live. My mods 1Z sounds it’s very wide. Compared to Romi 1Z, everything the same, same firmware, same iem, cable, same songs; Romi sounds very deep, theres very high ceiling and deep bottom, bass hits hard but sounds natural. Soundstage not as wide but everything else is just a couple step higher, very musical and dynamics with emotive vocals. I’m really curious how Romi sounds compared to NayParm modded Kaisei cap version, since Kaisei is basically caps that replace BG caps. It would be amazing to compare the 2 dap together
