I have subscribed to Stereophile continuously since 1975 (with some issues bought at news stands - remember those? since 1970) and TAS intermittently over that same period. I subscribe to both now only because I want to support the concept of high-end audio and those 2 periodicals continue to have the highest profile in this country. Too many of those to which I previously subscribed have vanished into the halls of history (e.g., Ultimate Audio, Fi, Listener, The Audio Critic, International Audio Review, and a few others) and some non-US mags (UHF, HiFi+, HiFi News, to each of which I have subscribed in the past) seem too representative of their principals' POV's.
In the end, the value of "reviews" of high-end audio for me depends entirely on the reviewer and what I know or have learned of his/her audio "tastes"; the ones I can relate to are few and spread across the emags currently populating the Internet. I suspect it is the same for many of us here.
