There is a website called DailyAudiophile which summarizes (with links) dozens of Audiophile e-zines. Not surprisingly each has a slightly different focus on the scene (hobby), with several mostly devoted to moderately priced equipment. The good news is that despite inflation, there are new monitors in the ~$5k range which probably sonically surpass those early '80's WATTs (although TBH I have never been a big fan of the Wilson "house sound").
As noted, manufacturers tend to charge what the market can bear; fortunately trickle down technology is also alive and well. As far as Stereophile and TAS, one can hardly blame their reviewers for wanting to hear and review the best components they can; again, if the marketplace continues to support the magazines there is no reason for them not to. Look at some of the other review sites if you want coverage of less expensive gear.
