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.
