Hi guys,
I have this 3-way crossover + sub output, I thought to make an update of it by replacing all the opamps present, they are BA4560. My idea of soldering dip8 sockets and so being able to insert and remove opamps. Do you think it's worth it? which opamp do you recommend affixed to the BA4560 type plug and play?
Thanks

The BA4560 is not bad. A NE5532 might drop right in. Take a look at the power supply and decoupling scheme.
This is an easier route, and may improve the Sonics.

.... strange, I have not heard much good about the AB4560 .... I have also attached the schematic
Not expensive enough.
If there were 60.00 USD discrete opamps you could read reviews where substituting these in changed peoples lives. Poorer but happier.
Two easy mods, Bypass C33 and C37. Also I see no local decoupling for the opamps. Add some close to the opamps. Being through hole construction add some small value caps close to the opamps.
