The book I mentioned was a christmas gift. I would guess if you enjoy Stereophile and TAS you will find the book useful.
I found the book interesting in certain passages. The sub phase and amplifier power parts were of interest. I tend to focus on maximizing the performance of gear (speakers) in rooms, rather than the gear itself. I have found Toole's Sound Reproduction book quite instructive for this.
The problem I found with the mags is they seldom cover the truly important aspects of audio. The core foundations of audio are not sexy or romantic. They wont sell more magazines or any gear so they are not often talked about. But damn do they make me want more stuff!
