It could have something to do with something else in the circuit, but I do not a have a schematic to make any conjectures.

Then, like I mentioned before, why don't you simply replace the resistors which establish the output and input impedances with something you deem more appropriate? You shouldn't need a schematic to be able to determine the location of these parts.
