Good points well made Mark, an excellent summary I think.

IMHO, a good power supply never hurts. PSRR is not a simple subject, and its rarely constant with frequency. Allen Wright makes a very important point in his book, along the lines of "points in the circuit that should stay fixed, should never move, and points that should move, should have nothing stopping them moving."
Good points also. This book Nick? Not cheap, but worth it?

All of which is interesting in context of Steve's latest 2A3 adventures.

Its a good read, but I was lucky I think in not buying it for many years, when I finally did, both myself and Andrew was amused to find we had developed the same circuits. It would have been far less fun to have just got them from the book in the first place :-)

I'd just like to point out here that it was not I but t'other Andrew. But I agree with what Mark just said.
Philosophers have only interpreted the world - the point, however, is to change it. No it isn't ... maybe we should leave it alone for a while.
