I have 2 active EQ / XO circuits that consist of an input buffer, filter circuits for the HP and LP, one with an output buffer attenuation / gain on the LP. One totolling 5 opamps and the other 7 opamps per channel for two different sets of active speakers.
I have a plenty of OPA2134s but have not used OPA627. Is it worthwhile to give it a try?
In my circuits, all opamps (but one) are used as unity gain buffers so I am not so sure if replacing the OPA2134 with OPA627 will give any audible sound improvements. Replacing the whole lot is too expensive but if only replacing the output buffer then I am wondering how the sound can be improved because distortions are accumulative.
What do you think?

Bill
