I am actually very happy with the bass if the right impedance is matched. But this dap being the best sq I have it's hard for me to be too critical.
At the end some earbuds are easier to drive than others. And perhaps ty hi z 400ohm is easier to drive than some as I read somewhere. Like Zen 320ohm seems much harder to drive than 600ohm puresounds from what I could get. I owned seahf 150 and asura 2. Seahf is much easier to drive but lack the refinement of asura 2. And to conclude, I have a 16ohm earbuds that needs amp to shine as well!
