I...don't have enough knowledge to answer that question I feel like it's a good investment...

Recently, after buffing down my quad IEM in an attempt to achieve better comfort, I though I had somehow managed to kill the DTEC driver because all the base disappeared. Turned out that I had removed just a few to many mm from the end of the tube and it totally changed the sound signature. I was able to resolve the problem by attaching a small bit of tubing to the end of the DTEC's sound port and the thump returned to my music.

Just asking, but has anyone managed to reproduce a decent 20Hz sine wave on IEMs? For all my tuning, I can only get a relatively flat response to 50Hz, and then rolling off to about 25-30 Hz before I lose all response.

Yes, but it depends on drivers - some drivers roll off some don't. Typically non-vented roll-off.

Could also be related to your test equipment and/or method of coupling to the mic, I rarley see a complete dropoff, even with non vented drivers.

Maybe my ears just aren't sensitive to 20Hz... I'm using a HODVTEC so I'd expect reasonable amounts of sub bass.
HODVTEC has quite good sub bass! I feel that it sounds better than the CI! Not sure how to improve the roll off though. Usually I see 10-20db roll off from 50 to 20Hz?

I'd say there's a sound leak somewhere, either from the tube to the receiver, the tube to the mold or the mold to the mic

Are you measuring it on open shell or bare drivers? I measured HODVTEC yesterday and while bare driver measured quite poorly it improved dramatically when I put my fingers near the vents almost closing them, bass improved and response was really good.
It's because HODVTEC having 4 quite large vents makes it seem as if the sound was leaking out.
The HODVTEC measured like CI even with the vents open for me o.O
How did you think they sounded? Was it CI or the HODVTEC for you, as a personal preference?

I didn't listen to it but if I was to pick ultimate woofer it would be 38DJP007Mi/8a - this is one is unbeatable right now. From what I know no other woofer performs like this

sonion's vented 3800
There is no non-vented 3800sonion's vented 3800
@muzo2 - as described it's Sonion 38DJP007Mi/8a
You can find this woofer in Roxanne, but Roxanne has two of those in each earpiece
