Ouch. Maybe it is worth to check how much will be shipping from the Audiophonics?

Just a remainder, “select grade” laterals are not P to N part matched at all and there is no reason not to order cheaper non-binned ones.
The binning is for paralleling them I believe. Matching n to p means adding some gate-source capacitance to match those up so the drivers see a symmetrical load, although I'm not sure its worth it as many circuits have the gates shorted to each other at AC anyway, and the internal capacitances are very non-linear anyway (its a MOS capacitor basically).
I think double-die devices are already bin-matched so that's going to be cheaper than matched single dies.
