This book is not a "cookbook" approach, but presents well researched and tested approaches. As such it is guaranteed to offend some people (evaluation of design changes and improvements is scientific, as opposed to subjective). Self uses the book to take a shot at much of the patently mumbo-jumbo in high end HiFi, which is entertaining! The book features the "blameless" amplifier and the circuit is given, but it would have been nice for the PCB layout (or a Gerber file..) to be included so that some quick experimentation can be done. The only minus (apart from that) is that there some areas not treated: Nested Differential Feeback loops being one. A very unique book, collecting together a lot of very valuable information.
