M1060’s and M1060C’s modded open back have been called mini LCD2C and many reviewers who note the LCD2C is overall better say that the bass on these alone actually outdoes the $800+ set. I posted in the deals thread they are both on sale vs the normal prices (atleast I have seen)
as well at the sundaras
also posted deals on sundara’s and HE-560 (admittedly don’t know a lot about those but they were once “$900” lol I guess the sundara’s were better tho)
here is the post
if bass is a concern outside of Argons I can’t think of anything better
