I’ve been playing around with parametric equalization to make my iem listening experience more enjoyable. I think I have found the answer although I’d guess it’s fairly subjective. Sub bass seems to increase the depth of music and actually seems to inject it with more emotion. Anyway, after some PEQ, my new sonic cannons are the TRI x HBB Kai. Bass cannons are a tie between QKZ x HBB Kahn, Kiwi Ears Cadenza, and Beyerdynamic DT770 PRO 32 Ohm.
I wish most reviews atleast spared some effort to show how much you can actually get out of your device if you EQ some. Not EQ-ing is like the flat earther equivalent of the audio world.
Although I would suspect that the DT770 at 32ohms has the least good bass in comparsion to the rest of their DT lineage. My DT900 pro x is a literal beast in comparsion to the also bass heavy Tinhifi P1 Max.
