Things can't have changed...
...that much, soooo...
In the olden days of of two-channel, analog music, when I actually gave a r@t's @$$ and subscribed to them, the hobby-related mags i.e. High Fidelity, Stereo Review and Audio, would run articles that were a basic primer for the neophyte and they would do this at least yearly. In said articles, terms, specs and related jargon were demystified...of course, this requires a monthly visit to your newsstand to see when and if such info is contained therein...
I know Stereo Review morphed into another more A/V oriented mag(the name of which escapes me). There are those who eschewed such mags(favoring the higher-end TAS, Stereophile etc.) because they seemed to never review a product they didn't like, but notwithstanding such critcisms, it was one of the more general purpose publications and it served that purpose well IMHO. The more high-falutin' ones seem to take a basic understanding of the subject matter as a given...as if only the "inner circle' were worthy enough.
The one thing re: mags is that they can expose you to other products and upcoming technologies a bit better than a "book" which may be outdated even as it's published...websites DO have promise, but a mag is certainly more portable. Me, I have more faith(perhaps misplaced) in something committed to paper and ink, than to some of the "experts" in cyberspace.
