Good question and hard to answer. Audeze is well known for their pleasing sound character and bass. Maybe try some tube amp or cooper cable. Or try LCD2/LCD3 pre fazor which was evidently warmer (I prefer new versions).
Warm headphone is definitely HD650 but it could be step back for you.
If you look for better headphone around similar price category then I would say it will be more question of taste than to say better. And moreover LCDX is in my opinion one of the best headphone in all category in terms of universal use, with spotify, across many genres, all in one system, search for new music etc...
But you can try electrostatic L700, O2mk2, Canorum (did not hear but seems like super adult hp). Another planars dynamic like Edition X...
If you do not have limit, HE1000 is definitely better headphone for me. I did not hear enough time LCD4, Abyss AB-1266 but this category is quite crazy pay for "only sound"...
