this is a very interesting book! I wrote an essay on it. it was difficult, I also had to ask the authors from Rush My Essay for help. they created an essay for me according to the standards I requested, quickly and inexpensively. And I was able to get a good grade.
Audio books
I have the original version of Robert Harley's Complete Guide To High End Audio, and have had Good Sound by Laura Deerborn... has anyone done anything more recent than those books?
