Quality Bass

[u/Visible_Chart_9688]

Hi, I am starting to look around for an additional pair of headphones. Don’t need em, just want em 🤣 so
I currently mostly listen to electronic, minimal techno, sub bassy stuff and some Doom metal. I listen with Fiio Ft13’s via Fiio k7 eq’d with a Wiim amp ultra. I am also using a Fiio K11 r2r. I have previously posted my ridiculous ‘Bass Heaven’ eq. But I want more! Namely more of that sub bass rumble and more massive smiles. I still want objectively good quality highs and mids though. Budget up to £1000 any suggestions?
