Posting on behalf of a friend on Discord (FatGoblin) who has bought, compared and graphed both Dawn and Red dawn:
"I got the IMR Dawn and a chap mentioned (on another discord server) that there was some controversy around it. After a bit of digging I found a company on Alibaba that had what looked like the same bullet IEM. I ordered a sample and it arrived today (had to ask for the DLC option as it wasn't listed). With shipping and taxes it was approx £70. It's sad to confirm but the $31 DLC bullet is the same 1-for-1 as the IMR £255 Dawn
At least in listening to it. Will measure it when I get time."
Big props to him for doing the digging and comparison all himself just to confirm everything thats going on.
EDIT: Adding onto this he has also mentioned the following:
"Yep. Sounds the same 100%. I did a bit of skulldugary with the seller on Alibaba and they told me they work with IMR. It's a drop-ship with an incredible markup. It sounds great, but they are identical. £70 for the sample set incl $39 shipping + taxes. If you buy 4000 it drops to $3.90 per set"
