I like its simplicity and relevance (to a consumer, not an engineer).
Of course it's simple. It's written by a simpleton. It's also written for simpletons—people who only want to be told what gear to buy, and don't realize how they have opened themselves to being hoodwinked. If you put any faith in that book, you are being hoodwinked. You might as well walk into an audio store, drop a wad of cash on the counter, and say, "Sell me anything you want."
I realize that it may not make a lot of sense to an audio connoisseur like you gentlemen.
The problem isn't that it doesn't "makes sense." The problem is that it's WRONG. Through and through. It will only appeal to people who don't know any better.
I hope you will help me with things I don't understand.
Why in the world would we "help you understand" things that are wrong?
