In short - ad846 is very hard to replace. This is a unique set of characteristics for the chip. Try to find the chip.

Default Here's another excellent sounding chip!

Though it is a dual, it sounds great when properly 'tamed'! Otherwise, it can be a wild one! Use a 'scope when deploying this filly!

@Romcat

Yes, try the LME49720HA (metal can). I can't explain but it sounds so much better than the plastic version.
