Oh okay. Thanks for that explanation. so 2k to 6k gentle dip, shall remember that!<Snip>
The Penon Fan 2 and Sony M9 are both lauded for their lush midrange (8 kHz is a coupler peak, measurements above 8 kHz are not accurate).
I suspect this is due to the gentle descend from 200ish Hz - 600 Hz (around the lower midrange), instead of a steep drop off like some other V-shaped IEMs. And both these IEMs are warm neutral and are not that bright in the upper treble, nor are the very bassy/basshead.
So this combination seems to add a lot of heft to the lower mids and lets it not be overshadowed by bass/treble?
If you like something like the Penon Fan 2, the next logical step up would be the Sony M7 and M9. The M9 is better than the Fan 2 in technicalities, but we are talking about 5x price differential and major diminishing returns. The M7 is just a tinge less technical than the M9, and not as good in soundstage/treble extension, but can hit around 80% - 90% or so of the M9 for substantially cheaper.
Just checked the graphs of couple other IEMs I like.
Aful p8: that slopes down from 200 to 300 may be before its already on the ascent by 4k in that lower mid range.
Sivga Nightingale: flatlines almost from 200 to 400, before gently dips to 900 almost
Also saw Aful One (which I haven't heard): it slopes pretty gently from 200 to almost 800 even ...
Z1R seems to slope gently from 200 to 400 before flatlining to 800
That Sony M7 seems to start the Great Gentle Dip from 90-100 hz itself, all the way to 800!
Anyways, thanks a ton. Will keep a look on the graphs if the mood seizes like today, and try to make sense if i can.
Of course, I can always blame stuff on burn-in (just kidding Carmoose! )
