Does the book compare no negative feedbck circuits vs. feedback circuits for noise? In addition, negtive feedback helps with power supply rejection and DC stability. If I remember all this correctly, what effect would that have on noise? I suspect that it would have some effect, but the incredibly high noise floors I have heard out of these units and in some cases measured from these units make me wonder.
In any case the quote you gave is esentially correct.
