That's a really tidy desk :P

How did you power the MEMS?

Ooh I like this type of tuning. Listen to it yourself and see if you can hear it, personally I usually keep those peaks since I can't hear them.

Ooh that is very interesting. Where did you buy the round ones?

Can you test a random IEM? Any one will do just to see if it is leaking. If you're using the original soundcard that came with the IEC711 it shouldn't need calibration.

What's your measurement setup? I'm pretty sure the 2ohm parallel resistor is ruining the measurements.

Ah sorry you need to low pass the 31618, I'm not sure of your tube lengths, but purely guessing, you can try using something like 20ohms in series, and 68uf in parallel. I usually trial and error this part lol

Perhaps try flipping the polarity of the HODVTEC, though I would still prefer to use a series resistor here instead of a parallel one.

2 ohm parallel? That's like shorting the driver isn't it?

What's the config of your iem?

Hmm, it seems that the two drivers' resonance peaks are very different right?

I see, how does it compare to SWFK? :P Is it harder to implement as well?

Looks amazing! How did you get the faceplate so nice and flat? What's your review on the RAU drivers?

Purely based on the two graphs I would suspect the blue to be better. However, I think green probably will sound more likeable to me personally.

This 6mm planar works like a planar (rather than say the Square Planar). But honestly the voice coil design still throws me off as it is wound more like a dynamic driver than a planar driver with its traces laid out.
