Yup. That is what I was saying. The vanilla op-amp balanced input has a number of severe limitations (unbalanced input impedances, noisy etc etc).

The way to go is either a buffered balanced input, which matches impedances; or to go for a specialised single chip solution like the THAT balanced receiver. Both of which are lower noise than the vanilla.
