I can't comment exactly on your ES model, but from what I know all Sony receivers use the same Infared codes. Almost all universal remotes can't learn your remote's component switches though, as they have a long series of codes that also turns devices on.

I also know that the Marantz RC-2000 will *not* work at all with my particular receiver, a GA8ES. Fortunantly, the RM-AV2000 works perfectly, and actually has alternate, shorter component switch commands.
