That’s it for now.
Twilight replaced my UP for male vocals.
8SL replaced the Variations & UP.
AMT16 replaced any future interest in planar IEMs for now.
How would you describe the special sauce of the AMT16?
Current Rotation:
GS Audio SE12 - by far my best sounding stage,bass,vocal,and extended highs magical find!
Letshuoer EJ07M - most technical set
Yanyin Canon 010 setting I used to love the bass but the BA bass of the SE12 kills it.
Fiio FH5S - unique in its presentation and outstanding build quality my MMCX
Choice
IKKO Obsidian OH10 - solid Bass slam all rounder.
TinHiFi P2 f to remind myself what a less bassy IEM sounds like.
Kinera BD005 Pro. When I want to remind myself what a sybliant IEM sound like.
Sorry that was 7 not 5

I have the same question as @Rcayn . If you wouldn’t mind, could you give us a little breakdown summary on the Goldplanars? They’re a set I just haven’t heard much about, but they definitely intrigue me. I’d like to know what they’ve got under the hood, so to speak, that puts them up with some elite company in that price range so I’d definitely appreciate any impressions you’d be down to share.
A lot of that is addressed here:
If we’re talking its most standout feature, it’s the timbre. It has this smooth/analog, but incredibly detailed aspect to the sound which is not dissimilar to most descriptions of amt ribbon speakers (I hesitate to call anything “electrostatic-like” since I haven’t heard one myself.) A lot of extension in both directions. A downside is it being very source-picky, both in power and to tamp down some of that upper treble (8k peak).
My list needs a change, there are some IEMs that will be gone from the previous list I posted.
