Its UP TO 50% better. I havent read through the whole book. its a rather large book and i just havent had the time yet. But i think thats the section on setting up the speakers in your room. but im not going to re type 20 pages of stuff so if you wanna know you'll just have to go read the book. Im not here to argue with people about stuff. im just simply saying that this is a good book for anyone interested in audio and its intersting reading and you would probbly learn something new thats all. If nobody goes out and buys it. hey not my loss but just as people reccomend music because they enjoy it, im reccomending this book because I enjoy it.
