Meteor is designed for phase sync though. It’s like the main design point of the meteor. And it has flat impedance curve as well.Now that I've recently added the Symphonium Meteor to my collection, I'm starting to think that my issues with EQing IEMs are actually specific to all-BA sets. While it's relatively hard to come by phase measurements for many IEMs (let alone, all-BA sets), those that I have found have impedance and phase graphs that look quite different from other sets, including hybrids/tribrids. This has me suspecting that multi-BA--or possibly just all-BA--sets are susceptible to phase smear when using (minimum-phase) EQ.
Admittedly, a sample size of two IEMs is hardly definitive. Without a measurement rig of my own or widespread impedance and phase (or even distortion) plots of many IEMs, I'll just have to rely on my ears. And my ears are telling me not to EQ either of my (all-BA) sets. I'll have to wait until I get another IEM with a different driver makeup to compare.
Curious if others have noticed a difference when EQing all-BA sets vs other driver combinations?
I don’t know why you are having much challenges with EQ given your expertise and previous experiences. I regularly apply EQ profiles from my W4 dongle on BA sets and they have been just fine. That smearing that I hear when using EQ from a micro DAP in the past is not there. It’s likely the implementation of EQ matters, and maybe IEM makes it easier to hear problem of the EQ?
