That username tho...
I own the M100s as well, and have owned the Noble 3Us previously. I checked out some impressions of the Dulce Bass as well (the reviewer clearly had new toy syndrome, but I took the facts).
The DB (or any IEM of BAs only) will not have the impact the M100s have. Those are excellent for bass, and they are 50mm drivers. You may get higher quality bass, but quantity, no. The DB looks like it would have less recessed mids and more present highs, but I am not sure about the soundstage. I would go for it, since it is Noble they are bound to be good anywahs. Hopefully someone who actually owns both can chime in, but hope I helped.
