Default susy opamp- nice

anybody have any tips tricks for susy i/v stage?

i had a nice success with differential 1543> opa1632> 1:1 trafo unbalancing.

vcomp fed with vref of 1543.

sounds uncannily like passive i/v, more so than any other active i/v i have tried. bigger dynamics, more detail, but not as impressive as stacked 844 in that regard.

i just added 200ohm feedback resistors on 1632 and nothing else.

any other tweaks i should try with this setup?
