My observation is that not many do not talk about a lot of things that used to get a lot of buzz here much anymore. I think a lot of it has to do with increased value proposition these days of more affordable and/or mainstream stuff. Of course esoteric tube amps, high efficiency speakers to match, esoteric tweaks of questionable value like expensive fuses, etc. still get some buzz. And some still offer good technical insights into issues not often discussed elsewhere when needed. Not looking good for the future of high end audio though unfortunately. The keys to good sound in general have been discussed quite thoroughly though over the years and those things tend to not change much.
