I already have 3rd edition of the book and this was planned to be logical continuation. The book brings you much more pages and as expected more information. It even more expands known author's attitude about importance of distortion which is probably not the only thing that borders amplifier user. If you are about to study deep and excellent distortion elimination phenomena, this book is your great source of information, both gathered from simulation and real measurement. The author is using attractive way to teach you about that. Due to that, book is not really meant as one and only cook book where you may find your recipe for amplifier design. It brings you knowledge, but id does not tell you how to cook. Although being a great source of information, reader is under impression that amp design is still a well kept secret.

This latest edition both builds and expands upon on, and takes forward, the material covered in the earlier editions. Although this is an in depth technical publication, and obviously aimed as such, it is non-the-less very readable and should benefit anyone who has even a passing interest in the subject of amplifier design. Those who already have a good grasp of the basics will find that the analysis and detail of the various circuit "building blocks" are covered in great detail with several complete designs being presented, designs that follow the principles outlined in the text.
Books of this calibre are rare indeed, this taking its place as one of just a very small handful I would recommend on the subject.

Audio Power Amplifier Design 6th edition by Douglas Self
This book, is no lightweight read in both senses of the word. Measuring 23.5cm tall, 19cm wide and 3.3cm thick (that's 718 pages) and weighing in at 1.31kg (or 2 ounces short of 3 lbs in old money) it takes a fair amount of stamina to hold but it's a joy to read otherwise. Yes, it's technical, but an otherwise dry subject matter is made more than palatable by Mr Self's equally dry wit which he wields to devastating effect as he methodically demolishes the props supporting the " Subjectivists' " views. I am sure he is too polite to call them "shamans and charlatans" but I feel less inhibited.
The book is aimed at an audience with some familiarity of the issues he addresses but those with more modest experience will still find it very valuable. Mr Self apologises for the lack of some "textbook" groundwork because this is already a large book lacks the space. He suggests instead that interested readers can find this information elsewhere. This is a shame. Perhaps this might be the subject of a companion volume.
In the systematic discussion of the sources of distortion, (Yes, this even includes the thermal noise in resistors), the book is generously illustrated with circuit diagrams and distortion graphs. Mr Self, with a constant eye on the practical, also shows how some commercial designs, with varying success, attempt to tackle the problems of distortion.
I'm pleased to note that the book has reached its 6th edition which indicates the appreciation, by many, of the development of Mr Self's arguments.

This is the definitive book on the subject, no nonsense, just hard facts, with no concession to pretentious subjectivist guff. No platinum speaker cables here (actually they would be rather bad!). As a very experienced analogue designer, I am still learning a lot from this book. But engineers will always disagree, there is more than one way of doing anything. I will not list my minor niggles, each of you will find your own. For instance, I always use Sziklai pairs, to make life simpler.
But if you fancy designing a power amp, this book is ESSENTIAL reading. It will save you lots of time, money and aggro, and help to ensure good results.
