Looks tyo me like it is saying that the FET's are more linear in an open loop config. but since BJT's amps can use more negative feedback to overcome this affect the end result can be more linear with BJT's. I've not really done much/any work with open loop design I guess I had jumped to a not entirely correct assumption. Interesting point.
