Fair enough, though I can't speak as to the quality of the raw drivers on the D9200. Which product mentions the N90Q?
The horn composite speaker is the same technology as in the OKCSC headphones, along with all of its issues.
The dual driver unit likely has either crossover or timbre issues (or both).
The Tiinlab unit has a deeper construction than most closed backs, so the soundstage might seem wide, but that also usually leads to mid and treble issues in an effort to provide balanced sound.
The cheap walnut item is definitely just a shell.
The MSR7 shell is just a shell.
And like I said before the planar looks remarkably like the Sundara, and almost costs as much.
The D9200 ones might be worth a look if that is the genuine driver, and the dual driver might be worth taking a shot at to see if crossovers have improved, but otherwise it's a bit iffy. Hope the feedback helped.
Sadly the D9200 drivers aren't authentic. The MSR7 is actually a replica of the original and not a shell. (Not sure if that's allowed here I'll remove if so.) Also, this seller claims to have a shell with N90Q drivers inside of them.
