For the beginner, Stereo Review was a good primer. Of course, it's main purpose was to sell ads, and to get freebies for the testers. I even blame them for the newer measurements manufactorers started using, "Power at 100cps, one channel driven", rather than full range with extreme frequency rolloff db's, etc. I don't remember their ever writing about damping factor or interactions of amps with the motor effects of moving speaker drivers.
