I NEED - best parametric eq under 300$ for dac/amp/stax

im looking for a good physical stereo parametric eq under 300$ with xlr in/outs to put
between my drop balanced dac an schiit magnius , id love one with knobs but i wouldn’t be

adverse to a digital interface ,i dont mind ordering European or Asian brands direct as long as
its not over 390$ to have shipped to the US also is ther a firmware update for the

DROP GRACE BALANCED DAC for linux or does it need one.

Schiit has the Lokius, which is a graphic EQ with knobs.

Parametric EQs are expensive when done simple and insane when done correctly.
