I recall devouring Stereophile back in day, small format digest sized with very little advertising, certainly much info in that what I believe was bi-monthly publication. But then I was beginner audiophile and no web, hungry to be educated.
Seems to me I found commercial audiophile publications less valuable as my systems improved. I recall going to audio shows when it seemed every system superior to mine, ate up information provided by manufacturer reps, designers, and the listening certainly elucidating. Over time as my system started to compete and/or sound superior to what I was hearing at these shows, they became less valuable, just like the publications.
I wonder if the audiophile publications are as valuable to today's novice as they were for me back in the day. Should be mindful of the reams of great information found on web, certainly makes these publications less valuable.
So bottom line, don't know if publications have changed, or is it more about how we've changed?
