The Spectrum's print edition is exceptional; That being said though, any moderate technologist can read the Spectrum. The Spectrum is not a collection of whitepapers, but a series of articles on broad topics and even investigative reporting that I wish were more mainstream (e.g. Dec. 2009 article on what its like to run an electrical generating station in Gaza). Pretty much any Wired reacher can handle it if they can stand not having a liquor ad on every other page.
