looking for a mod that bypasses the filters (probably keeps the high trim) and leaves only the crossover part (2 low cuts and the step filter per band. That (with High trim kept) leaves 4 ICs. OPA2134 had been done by ZenPro, Jim Williams advised LME49720 (aka LM4562). Any consensus on those ICs?
EDIT:found a LOT of positive comments about LME49860, I am tending to settle on that chip.
