After reading it, I don't see a whole lot to argue about. There aren't any hard black or white issues presented. I do agree that most issues when people are comparing different components boil down to level matching.
There is so much hype in the audio industry that a lot of components appear because someone invents a new "problem" and that presents a mega dollar fix for it. As long as audio is a hobby to you, spend your money as you see fit and enjoy the music. OTOH, obsession can lead to a host of woe's.
